New information of the biodiversity of the nymphalid family (Insecta, Lepidoptera, Nymphalidae) species collected in Romania’s fauna between 1887–1984
Authors: Stancă-Moise Cristina , Moise George , Brereton Tom , Stanciu Mirela
Published: January 2023

This paper complements the data published thus far about species of the nymphalid family with data collected in Romania’s eight regions between 1887 and 1984 and elsewhere in Europe (Austria, Germany, Croația, the Republic of Moldova, Serbia and Switzerland), including the date and the site of original collection. For the first time, this research presents the collecting information of the species held in the entomological collection of the Museum of Natural History in Sibiu. It identifies the species of the nymphalid family in six of the museum’s lepidoptera collections. These collections are of extraordinary interest not least because they are associated with natural scientists of European renown, such as Daniel Czekelius, Eugen Worell, Viktor Weindel, Rolf Weirauch, Heinrich Hann von Hannenheim and Eckbert Schneider. The analysis, cataloguing, centralisation and updating of the nomenclature resulted in a number of 1,865 specimens from 49 species and fifteen genera (of the 90 referenced in Romania’s fauna):Aglais,Apatura,Araschnia,Argynnis,Brenthis,Boloria,Euphydryas,Inachis,Issoria,Libythea,Limenitis,Melitaea,Neptis,NymphalisandPolygonia.Data published in a previous article add 101 specimens from theVanessagenus.

Most species originate regionally from the nine counties of Transylvania followed by Oltenia and Moldova (three counties each), Banat and Dobrogea (two counties each), Crișana, Satu Mare and Muntenia (one county each) and the capital of Romania, Bucharest. The species presented in this paper also include the extinct taxonPolygonia egea(Cramer, 1775), Eugen Worrell collection and three species that are endemic to Romania:Melitaea retyezaticaDiöszeghy, 1930,Argynnis pandora dacicaHormuzaki, 1892, Daniel Czekelius collection andBoloria pales([Denis & Schiffermüller], 1775)carpathomeridionalisCrosson et Popescu-Gorj, 1963, both in the Viktor Weindel collection.
Simulation of time to failure of porous dielectric in advanced topology integrated circuit metallization system
Authors: Orlov Andrey A. , Rezvanov Askar A.
Published: January 2023

In this work, the simulation of the processes of diffusion of metal barrier ions into a low-k dielectric between two nearby copper lines was performed. Based on experimental data on the diffusion coefficient published in the scientific literature and calculations according to the mathematical model of the distribution of metal barrier ions in the dielectric, the time dependent breakdown of a porous low-k dielectric in the elements of very large-scale integrated circuits of the modern topological level was estimated. Additionally, the work obtained dependences of the dielectric breakdown time on the distance between two nearby copper lines along with dependence on the power voltage of the line (the other line is grounded).

Published: January 2023

Anredera cordifolia (Ten.) Stennis, also known as Binahong (B), is an Indonesian plant used to treat diabetes. The purpose of this study was to determine the best extragent for preparing Binahong extract as an antidiabetic agent using different concentrations of ethanol (50%, 70%, and 96%), labelled as BE50%, BE70%, and BE96%. An alpha-glucosidase inhibiting assay was used to assess the activity. The most active extract was tested in vivo assay using an oral glucose tolerance test (OGTT) and alloxan-high feed diet (alloxan-HFD)-induced diabetes in rats, with glucose level and beta cell Langerhans repair as parameters. A molecular assay was also performed to look into the expression of homeostasis regulator genes on 3T3-L1 adipose cells. The results showed that 96% ethanol extract (BE96%) inhibited alpha-glucosidase the most effectively (IC50 119.78± 11.14 μg/mL). The in vivo assay revealed that the treatment BE96% at 250 mg/kg BW for 21 consecutive days significantly reduced plasma glucose levels in Type 2 DM rats compared to the control group (p ≤ .05) with improved of Langerhans beta cells. BE96% also significantly reduced postprandial glucose levels. At the cellular level, Oil-Red-O staining revealed that differentiated adipocytes treated with BE96% had the highest lipid absorbance (p ≤ .05), compared to the control. BE96% significantly increased the expression of Glucose Transporter Isoform 4 (GLUT4) at the molecular level. It could be concluded that BE96% exhibited the best antidiabetic properties.
The association between Vitamin D levels and postpartum depression: a review
Authors: Prijadi Shannon Maidelaine , Kusuma Clara Fernanda , Puspitasari Irma Melyani
Published: January 2023

According to WHO, Postpartum Depression (PPD) occurs in 10–15% of women after giving birth. Several studies assumed that vitamin D deficiency might worsen PPD symptoms. However, the association between vitamin D levels and PPD is still conflicting. This article summarizes the association between vitamin D levels and PPD. A literature search about Vitamin D levels and PPD from Scopus and PubMed databases was performed in June 2022. Eleven studies were obtained out of 30 studies. Nine out of 11 studies showed that vitamin D levels were significantly associated with PPD. However, the two others showed no significant association. The difference in the blood sample taken and how to assess depression contributes to a different result. The association is related to the role of vitamin D in mood regulation, synthesis of neurotransmitters, stimulating brain receptors, and intercellular neuronal signaling systems.
More than 80 years without new taxa: analysis of morphological variation among members of Mexican Aeneolamia Fennah (Hemiptera, Cercopidae) support a new species in the genus
Authors: Armendáriz-Toledano Francisco , López-Posadas Misael Adrián , Utrera-Vélez Youssef , Romero Nápoles Jesús , Castro-Valderrama Ulises
Published: January 2023

The genus Aeneolamia includes eight described species and 32 subspecies widely distributed in America. In Mexico, two species (A. contigua and A. albofasciata) and one subspecies (A. contigua campecheana) are recognized. In a recent study of Cercopidae in Mexico, a new species of Aeneolamia was noted from Oaxaca, Mexico based on body color and the ornamentation patterns of tegmen, without a formal taxonomic description. To test the hypothesis of an extant new taxon within the genus a comprehensive analysis of intraspecific morphological variation from 46 morphological features was performed, four related to tegmen color patterns in both sexes, six to male genitalia, and 36 continuous characters measured in specimens of both sexes of Mexican Aeneolamia from several geographical localities using traditional univariate, multivariate morphometric, and geometric morphometric methods. This is the first time that this approach has been used in Cercopidae. Aeneolamia danpecki Castro, Armendáriz & Utrera, sp. nov. from Oaxaca showed pronounced morphological differences in tegmen coloration patterns, the shape of different elements of the male genitalia, and body measurements compared to the other Mexican members of Aeneolamia; therefore, it is described as a new species.

Published: January 2023

Patellofemoral complications following total knee arthroplasty (TKA) are some of the most commonly cited complications in the literature, accounting for up to 50% of secondary procedures in the literature. Lateral dislocation of the patella, while rare, is one of many causes of extensor mechanism dysfunction. We sought to evaluate a novel patellar centralization procedure by comparing patients' pre- and postoperative clinical and radiographic data. A retrospective case-series study was performed on 12 patient knees (5 male and 7 female) presenting with ambulatory dysfunction due to laterally dislocating patella. All of the knees had component revision combined with hamstring autograft tendon weave and medial reefing of the retinaculum and vastus medialis. The results revealed reliable stabilization of the patella and improved extensor lag at a mean 2.2±2.2 years' short-term follow-up, which correlated with improved postoperative radiographic measurements. Range of motion in both flexion and extension was improved postoperatively. Improvements in radiographic measures of patellar tilt and patellar displacement were statistically significant, with reductions in the mean patellar tilt from 41.5°±25.9° to 3.9°±13.7° (
P
=.004), and in the mean patellar displacement from 2.8±2.1 cm to 0.8±0.9 cm (
P
=.012). Our study findings support the use of the extensor mechanism centralization procedure with autograft hamstring in management of laterally dislocating patella after TKA. [

Published: January 2023

Despite best intentions, health care disparities exist and can consequently impact patient care. Few studies have examined the impact of disparities in pediatric orthopedic populations. The current study aimed to determine if the treatment type or complication rates of supracondylar, both-bone forearm, or femur fractures are associated with race, ethnicity, sex, or socioeconomic status. The New York Healthcare Cost and Utilization Project's database was used to identify all pediatric patients treated for supracondylar humerus fractures, both-bone forearm fractures, and femoral shaft fractures in 2016. Risk-adjusted relationships with race, ethnicity, sex, hospital location, and median income by zip code were assessed with multivariable logistic regression. Patients who were non-White, resided in the zip codes with the lowest median income (<$42,999 annually), and were treated in metropolitan areas were more likely to receive nonoperative treatments for supracondylar humerus fractures. Female patients with a femoral shaft fracture were less likely to be treated with open reduction and internal fixation vs intramedullary fixation. Finally, complications were not associated with patient race, sex, or socioeconomic statuses. These findings bring attention to health care disparities in the treatment of common pediatric orthopedic fractures. Further studies investigating the underlying etiology behind these disparities are warranted. [

Toll-like receptor 9 is involved in the induction of galectin-9 protein by dietary anti-allergic compound fucoidan
Authors: Ezan Gnagnan J. E. , Mizuno Masashi
Published: January 2023

Dietary intervention of fucoidan extracted from Saccharina japonica brown seaweed has been ascertained to favor an increase of galectin-9 protein in the intestine of allergic mice, resulting in the attenuation of the food allergy symptoms. The molecular mechanism underpinning that galectin-9 secretion remains unclear. Recently, some evidence has suggested an implication of Toll-like receptor 9 (TLR9) in galectin-9 secretion. However, no investigation has been done. For this study, we aimed to understand the relationship between galectin-9 production and fucoidan intake, which will improve the therapeutic use of fucoidan in allergy treatment. Intestinal epithelial cells (IECs) were cultured in solid or transwell plates and apically exposed to fucoidan solutions and/or synthetic TLR9 agonist (CpG-ODN). The transcriptional response of the cells to galectin-9 (lgals9) and the TLR9 gene was evaluated by using q-RTPCR, and the protein expression of galectin-9 was analyzed by conducting an ELISA test. Knockdown of TLR9 in IECs was performed by targeting TLR9 siRNA, and its effect on galectin-9 release was assessed. We found that the interaction of fucoidan and IECs resulted in the upregulation of galectin-9 released in a dose- and time-dependent manner. The increase was further potentiated in combination with the TLR9 agonist. Fucoidan exposure to IECs tended to increase the mRNA expression of TLR9 in a way similar to that of the TLR9 agonist effect, and knockdown of TLR9 in IECs resulted in a decreased tendency of fucoidan-induced galectin-9 protein. TLR9 activation is therefore involved in the increased release of galectin-9 protein observed in IECs upon fucoidan exposure.

On Modified Erdős-Ginzburg-Ziv constants of finite abelian groups
Authors: Hu Yuting , Peng Jiangtao , Wang Mingrui
Published: January 2023

Let $ G $ be a finite abelian group with exponent $ \exp(G) $ and $ S $ be a sequence with elements of $ G $. We say $ S $ is a zero-sum sequence if the sum of the elements in $ S $ is the zero element of $ G $. For a positive integer $ t $, let $ \mathtt{s}_{t\exp(G)}(G) $ (respectively, $ \mathtt{s}'_{t\exp(G)}(G) $) denote the smallest integer $ \ell $ such that every sequence (respectively, zero-sum sequence) $ S $ over $ G $ with $ |S|\geq \ell $ contains a zero-sum subsequence of length $ t\exp(G) $. The invariant $ \mathtt{s}_{t\exp(G)}(G) $ (respectively, $ \mathtt{s}'_{t\exp(G)}(G) $) is called the Generalized Erdős-Ginzburg-Ziv constant (respectively, Modified Erdős-Ginzburg-Ziv constant) of $ G $. In this paper, we discuss the relationship between Generalized Erdős-Ginzburg-Ziv constant and Modified Erdős-Ginzburg-Ziv constant, and determine $ \mathtt{s}'_{t\exp(G)}(G) $ for some finite abelian groups.
Spanish Culture as a Key Aspect of the Content of the Brewing Industry
Authors: Martínez Eva Citlali
Published: January 2023

In social gatherings, gastronomic shows, festivals, and any type of celebration, it is feasible that the figure of a beer appears. This amber-colored product with a flavor that extends over a range of different bitternesses has become a symbol within Spanish gastronomic culture, achieving international projection. In recent years, the beer sector has established itself as an agri-food benchmark in Spain; however, beer sales are directly related to tourism, with countries such as Great Britain, France, and Germany being the main emitters of tourists (Más et al., 2002). In this sense, the communication of beer brands also has an influence, because it can shape the attitude of consumers towards this product, and it is at this moment when a challenge arises for the different companies (Trifonas et al., 2008), because they spread the idea that a certain brand generates better experiences. Therefore, this article analyzes the branded content of three brands: Mahou, Estrella Galicia, and Cruzcampo.

Published: January 2023

This study aims to examine the effect of good corporate governance (GCG) on financial distress in companies listed on the Indonesian Sharia Stock Index. The purposive sampling method was used, obtaining 23 samples that met the criteria. Panel regression and machine learning were used to test the hypothesis. Based on the results, the variables of GCG, which consist of institutional ownership (IO), managerial ownership (MO), board of commissioners size (BoC), and proportion of independent commissioners (PI), affect financial distress simultaneously, whereas BoC and PI are partially the most significant variables. The machine learning method shows that extra trees is the best model to analyze financial distress. The model indicates the most significant variable is IO, followed by BoC and PI. From the result, Islamic issuers should manage their GCG by reducing the number of BoC, IO, and adding a proportion of PI to minimize the case of financial distress.

Published: January 2023

Cannabis policy controls and regulatory changes have attracted a lot of attention across the world as the drive for full cannabis commercialization gathers momentum. The diversity of views on cannabis regulation reflects a melting pot of regulatory regimes (Aguilar et al., 2018; Seddon and Floodgate, 2020). This chapter is therefore an attempt to converge fragmented pieces of knowledge on cannabis policies and regulations. Using a qualitative research approach, the study found that cannabis policies and regulations in Zimbabwe and most countries of the world are at experimental stages and have to negotiate a family of challenges to succeed. For the cannabis industry sector to flourish, making sense of the policy tools that have worked in other countries and adopting supportive policy best practices to strengthen the cannabis policy and regulatory framework in Zimbabwe is crucial. The chapter ends by proposing ways of strengthening the cannabis policy framework in Zimbabwe.

Published: January 2023

The topic of cannabis has been widely researched over the years, but still remains a controversial yet interesting field of study. As an industry, the cannabis industry has evolved and developed over the years. The plant was previously utilized mainly by individuals for personal consumption, but following much research and development into the topic it has now become a lucrative market. Some countries have legalized cannabis or have gone through the decriminalization process. In recent times, the recreational usage of the cannabis plant has become a major source of interest as more investment and research has been made into the industry as a means to innovate more recreational cannabis products. There are now cannabis products like oil, beauty and skin care products, beverages, chocolate, capsules, gummies, and dog treats. The chapter is based on a qualitative approach as the aim is to gather a greater understanding of the phenomenon and provide insight for future research.

Authors: Grant Jacqueline
Published: January 2023

The cannabis industry, although shrouded with controversy due to stigmatization, has the potential to substantially enhance the economies of countries and assist with alleviating unemployment. The industry is projected to be worth some two hundred and seventy-two billion dollars by 2028. Besides the commonly understood medicinal properties, the plant has broad applications for use in construction, food products, toiletries, paper, and furniture. Following the devastation of the coronavirus pandemic and the looting in July 2021, the South African government needs to pursue alternative revenue streams. Public debt is mounting, unemployment figures continue to rise, and the economy is strained. This chapter thus seeks to offer insight into the contribution that the cannabis industry could provide in assisting the ailing economy and in alleviating unemployment.
The Legalisation of Cannabis
Authors: Luthuli Manono Malusi , Khumalo Njabulo
Published: January 2023

In recent years, cannabis has been one of the substances that many countries around the world have taken or are taking steps to legalise for certain kinds of consumption. In some countries, it is only legal in certain parts and still illegal in others. There is literature to suggest that idea of legalising cannabis tends to divide opinion with some people being for its legalisation and others being against it. The reason for the division of opinion regarding the legalisation of cannabis can be traced back to the many challenges and benefits that stem from cannabis being legal in any given society. There is sparse literature addressing the contextual dynamics of these resulting challenges and benefits. In this chapter, the authors present a commentary of some of the challenges and benefits that may result from the legalisation of cannabis in South Africa.

Published: January 2023

Purpose 17β-Estradiol (E2) supplementation suppresses MC38 tumor growth by downregulating the expression of programmed death-ligand 1 (PD-L1). This study aims to figure out the gut microbiota that respond to anti–PD-L1 and/or estrogen treatment in MC38 colon cancer model.Materials and Methods A syngeneic colon tumor model was developed by injection of MC38 cells into C57BL/6 background male and female mice. Three days before MC38 cells injection, E2 was supplemented to male mice daily for 1 week. Male and female mice with MC38 tumors (50-100 mm3) were injected with anti–PD-L1 antibody. Fresh feces were collected 26 days after injection of MC38 cells and 16S rRNA metagenomics sequencing of DNA extracted from feces was used to assess gut microbial composition.Results At the taxonomic family level, Muribaculaceae was enriched only in the MC38 male control group. In male mice, linear discriminant analysis effect size analysis at the species level revealed that the four microorganisms were commonly regulated in single and combination treatment with anti–PD-L1 and/or E2; a decrease in PAC001068_g_uc and PAC001070_s (family Muribaculaceae) and increase in PAC001716_s and PAC001785_s (family Ruminococcaceae). Interestingly, in the anti–PD-L1 plus E2 group, a decrease in opportunistic pathogens (Enterobacteriaceae group) and an increase in commensal bacteria (Lactobacillus murinus group and Parabacteroides goldsteinii) were observed. Furthermore, the abundance of Parabacteroides goldsteinii was increased in both males and females in the anti–PD-L1 group.Conclusion Our results suggest that gut microbial changes induced by the pretreatment of estrogen before anti–PD-L1 might contribute to treatment of MC38 colon cancer.

Do global attractors depend on boundary conditions?
Authors: Fiedler Bernold
Published: January 2023

We consider global attractors of infinite dimensional dynamical systems given by dissipative partial differential equations

u_t=u_{xx}+f(x,u,u_x)

on the unit interval

0 < x < 1

under separated, linear, dissipative boundary conditions. Global attractors are called orbit equivalent, if there exists a homeomorphism between them which maps orbits to orbits. The global attractor class is the set of all equivalence classes of global attractors arising for dissipative nonlinearities

f

. We show that the global attractor class does not depend on the choice of boundary conditions. In particular, Dirichlet and Neumann boundary conditions yield the same global attractor class.
$p$-adic Fourier theory

Q_p

-analytic functions on

Z_p

and showed that it is isomorphic to the ring of rigid functions on the open unit disk over

C_p

. Lazard showed that this ring has a divisor theory and that the classes of closed, finitely generated, and principal ideals in this ring coincide. We study the space of locally

L

-analytic functions on the ring of integers in

L

, where

L

is a finite extension of

Q_p

. We show that the dual of this space is a ring isomorphic to the ring of rigid functions on a certain rigid variety

, but not over any discretely valued extension field of

L

; it is a “twisted form” of the open unit disk. In the ring of functions on

X

, the classes of closed, finitely generated, and invertible ideals coincide, but unless

L=Q_p

not all finitely generated ideals are principal. The paper uses Lubin–Tate theory and results on p-adic Hodge theory. We give several applications, including one to the construction of p-adic

Severi-Brauer varieties of semidirect product algebras.
Authors: Krashen Daniel
Published: January 2023

A conjecture of Amitsur states that two Severi-Brauer varieties are birationally isomorphic if and only if the underlying algebras are the same degree and generate the same cyclic subgroup of the Brauer group. It is known that generating the same cyclic subgroup is a necessary condition, however it has not yet been shown to be sufficient. In this paper we examine the case where the algebras have a maximal subfield

K/F

of degree

n

with Galois closure

E/F

whose Galois group is of the form

C_n \rtimes H

, where

E^H = K

and

|H|

is prime to

n

. For such algebras we show that the conjecture is true for certain cases of

n

and

H

. In particular we prove the conjecture in the case that

G

is a dihedral group of order

2p

, where

p

is prime.
Tropical convexity
Authors: Develin Mike , Sturmfels Bernd
Published: January 2023

The notions of convexity and convex polytopes are introduced in the setting of tropical geometry. Combinatorial types of tropical polytopes are shown to be in bijection with regular triangulations of products of two simplices. Applications to phylogenetic trees are discussed.
Dihedral Galois representations and Katz modular forms
Authors: Wiese Gabor
Published: January 2023

We show that any two-dimensional odd dihedral representation 

\rho

over a finite field of characteristic

p>0

of the absolute Galois group of the rational numbers can be obtained from a Katz modular form of level 

N

, character 

\epsilon

and weight 

k

, where

N

is the conductor,

\epsilon

is the prime-to-

p

part of the determinant and

k

is the so-called minimal weight of 

\rho

. In particular,

k=1

if and only if

\rho

is unramified at 

p

. Direct arguments are used in the exceptional cases, where general results on weight and level lowering are not available.
Irregularity and $p$-adic Swan conductor
Authors: Marmora Adriano
Published: January 2023

Let

p

-adic differential equation.
Stability in level 0, for the odd orthogonal $p$-adic groups
Authors: Moeglin Colette
Published: January 2023

The general problem we discuss in this paper is how to prove stability properties for a linear combination of characters of irreductible discrete series of p-adic groups. Here we give ideas on how to reduce the case where the Langlands parameter is trivial on the wild ramification group to the case where this Langlands parameter factorizes through the Frobenius; we handle only the case of an odd orthogonal group. The principal result is that the localization commutes with the Lusztig's induction.
Non-Hausdorff groupoids, proper actions and $K$-theory
Authors: Tu Jean-Louis
Published: January 2023

Let

G

be a (not necessarily Hausdorff) locally compact groupoid. We introduce a notion of properness for

G

, which is invariant under Morita-equivalence. We show that any generalized morphism between two locally compact groupoids which satisfies some properness conditions induces a

C^*

-correspondence from

C^*_r(G_2)

to

C^*_r(G_1)

, and thus two Morita equivalent groupoids have Morita-equivalent

C^*

-algebras.

An invariant of quadratic forms over schemes
Authors: Szyjewski Marek
Published: January 2023

A ring homomorphism

e^0:\; W(X)\rightarrow EX

from the Witt ring of a scheme

X

into a proper subquotient

EX

of the Grothendieck ring

K_0(X)

is a natural generalization of the dimension index for a Witt ring of a field. In the case of an even dimensional projective quadric

X

, the value of

e^0

\mathcal{ E}

\mathcal{ V}_0

of the Swan sheaf

\mathcal{ U}

with the trace of a product as a bilinear form

\theta

is outside of the image of composition

W(F)\rightarrow W(X)\rightarrow E(X)

. Therefore the Witt class of

is not extended.
Localization of the essential spectrum for relativistic $N$-electron ions and atoms
Authors: Jakubassa-Amundsen D.H.
Published: January 2023

The HVZ theorem is proven for the pseudorelativistic

N

-electron Jansen-Hess operator

(2\leq N \leq Z)

which acts on the spinor Hilbert space

{\mathcal{A}}(H_1({\Bbb R}^3) \otimes {\Bbb C}^4)^N

where

{\mathcal{A}}

denotes antisymmetrization with respect to particle exchange. This 'no pair' operator results from the decoupling of the electron and positron degrees of freedom up to second order in the central potential strength

Statistics of lattice points in thin annuli for generic lattices
Authors: Wigman Igor
Published: January 2023

We study the statistical properties of the counting function of lattice points inside thin annuli. By a conjecture of Bleher and Lebowitz, if the width shrinks to zero, but the area converges to infinity, the distribution converges to the Gaussian distribution. If the width shrinks slowly to zero, the conjecture was proven by Hughes and Rudnick for the standard lattice, and in our previous paper for generic rectangular lattices. We prove this conjecture for arbitrary lattices satisfying some generic Diophantine properties, again assuming the width of the annuli shrinks slowly to zero. One of the obstacles of applying the technique of Hughes-Rudnick on this problem is the existence of so-called close pairs of lattice points. In order to overcome this difficulty, we bound the rate of occurence of this phenomenon by extending some of the work of Eskin–Margulis–Mozes on the quantitative Openheim conjecture.
Automorphism groups of Shimura varieties

In this paper, we determine the scheme automorphism group of the reduction modulo

p

. The result is very close to the characteristic 0 version studied by Shimura, Deligne and Milne-Shih.
Compactification of degenerate abelian schemes over a regular divisor
Authors: Rozensztajn Sandra
Published: January 2023

We consider a semiabelian scheme

G

over a regular base scheme

S

, which is generically abelian, such that the points of the base where the scheme is not abelian form a regular divisor

S_0

. We construct a compactification of

G

, that is a proper flat scheme

P

over the base scheme, containing

G

as a dense open set, such that

P_{S_0}

is a divisor with normal crossings in

P

. We also show that given an isogeny between two such semiabelian schemes, we can construct the compactifications so that the isogeny extends to a morphism between the compactifications.
Integer-valued quadratic forms and quadratic Diophantine equations.
Authors: Shimura Goro
Published: January 2023

We investigate several topics on a quadratic form

\Phi

over an algebraic number field including the following three: (A) an equation

\xi\Phi\cdot {}^t\xi=\Psi

for another form

\Psi

of a smaller size; (B) classification of

\Phi

over the ring of algebraic integers; (C) ternary forms. In (A) we show that the “class” of such a

\xi

determines a “class” in the orthogonal group of a form

\Theta

such that

\Phi \approx\Psi\oplus\Theta

. Such was done in [S3] when

\Psi

is a scalar. We will treat the case of nonscalar

\Psi

, and prove a class number formula and a mass formula, both of new types. In [S5] we classified all genera of

\mathbf Z

-valued

\Phi.

We generalize this to the case of an arbitrary number field, which is topic (B). Topic (C) concerns some explicit forms of the formulas in (A) when

\Phi

is of size 3 and

\Psi

is a scalar.
The supersingular loci and mass formulas on Siegel modular varieties

We describe the supersingular locus of the Siegel 3-fold with a parahoric level structure. We also study its higher dimensional generalization. Using this correspondence and a deep result of Li and Oort, we evaluate the number of irreducible components of the supersingular locus of the Siegel moduli space

De Rham-Witt cohomology and displays
Authors: Langer Andreas , Zink Thomas
Published: January 2023

Displays were introduced to classify formal

p

-divisible groups over an arbitrary ring

R

where

p

is nilpotent. We define a more general notion of display and obtain an exact tensor category. In many examples the crystalline cohomology of a smooth and proper scheme

X

over

R

carries a natural display structure. It is constructed from the relative de Rham-Witt complex. For this we refine the comparison between crystalline cohomology and de Rham-Witt cohomology of [LZ]. In the case where

R

is reduced the display structure is related to the strong divisibility condition of Fontaine [Fo].

Construction of eigenvarieties in small cohomological dimensions for semi-simple, simply connected groups
Authors: Hill Richard
Published: January 2023

We study low order terms of Emerton's spectral sequence for simply connected, simple groups. As a result, for real rank 1 groups, we show that Emerton's method for constructing eigenvarieties is successful in cohomological dimension 1. For real rank 2 groups, we show that a slight modification of Emerton's method allows one to construct eigenvarieties in cohomological dimension 2.

Geometric methods for cohomological invariants
Authors: Guillot Pierre
Published: January 2023

We explain how to exploit Rost's theory of Chow groups with coefficients to carry some computations of cohomological invariants. In particular, we use the idea of the «stratification method» introduced by Vezzosi. We recover a number of known results, with very different proofs. We obtain some new information on spin groups.

We consider the Schrödinger operator with a constant magnetic field in the exterior of a compact domain on the plane. The spectrum of this operator consists of clusters of eigenvalues around the Landau levels. We discuss the rate of accumulation of eigenvalues in a fixed cluster.
Hopf-bifurcation in systems with spherical symmetry. I: Invariant tori
Authors: Leis Christian
Published: January 2023

A Hopf-bifurcation scenario with symmetries is studied. Here, apart from the well known branches of periodic solutions, other bifurcation phenomena have to occur as it is shown in the second part of the paper using topological arguments. In this rst part of the paper we prove analytically that invariant tori with quasiperiodic motion bifurcate. The main methods used are orbit space reduction and singular perturbation theory.
