description: We consider the Cahn-Hilliard equation on a manifold with conical singularities and show the existence of bounded imaginary powers for suitable closed extensions of the bilaplacian. Combining results and methods from singular analysis with a theorem of Clement and Li we then prove the short time solvability of the Cahn-Hilliard equation in Lp-Mellin-Sobolev spaces and obtain the asymptotics of the solution near the conical points. We deduce, in particular, that regularity is preserved on the smooth part of the manifold and singularities remain confined to the conical points. We finally show how the Allen-Cahn equation can be treated by simpler considerations. Again we obtain short time solvability and the behavior near the conical points.

description: The ratio of shear viscosity over entropy density in low energy heavy-ion collision has been calculated by using the Green-Kubo method in the framework of an extended quantum molecular dynamics model. After the system almost reaching a local equilibration for a head-on $^{40}$Ca+$^{100}$Mo collision, thermodynamic and transport properties are extracted. Meanwhile, iso-vector giant dipole resonance (IVGDR) of the collision system is also studied. By the Gaussian fits to the IVGDR photon spectra, the peak energies of IVGDR are extracted at different incident energies. The result shows that the IVGDR peak energy has a positive correlation with the ratio of shear viscosity over entropy density. This is a quantum effect and indicates a difference between nuclear matter and classical fluid.

The power of who you know: an explorative study of wasta and justice perceptions in Saudi universities
Creators: name: Almutairi, Mohammed Abdulkarim
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Wasta is an Arabic word that refers to a reliance on personal relationships to achieve particular outcomes, and is problematic and controversial in Saudi Arabia. People form these relationships either directly, or through a waseet – a mediator who goes between the seeker of wasta and its provider. There are a few wasta relationship bases that encourage wasta to occur but do not necessarily result in it. These bases include immediate family, tribal relations, seniority, job status and social standing. Wasta is perceived negatively in the literature, whereas there is ambiguity surrounding every aspect of wasta in practice. This study uses qualitative and interpretative approaches to capture the perceptions of Saudi university faculty members regarding wasta and justice in their universities. Nine semi-structured interviews were carried out. The study found that inaccurate religious perspectives, unclear and insufficient regulations and ineffective management practices are factors that can explain the confusion around the acceptability of wasta and, thereby, its prevalence. Wasta is perceived to be unfair because it interferes with outcomes allocation processes and affects the accuracy and efficiency of management practices.

description: We study an abstract linear operator equation on a Banach space by using the inverse of the sum of two sectorial operators. We prove that the boundedness of a special type of operator valued $H^\infty$-calculus is sufficient for maximal regularity of the solution. We apply the result to the abstract parabolic problem, to give a maximal $L^{p}$-regularity condition. We also study the abstract hyperbolic problem and give a sufficient condition for the existence of solution.

description: We consider Hamiltonian systems driven by multi-dimensional Gaussian processes in rough path sense, which include fractional Brownian motions with Hurst parameter $H\in(1/4,1/2]$. We indicate that the phase flow preserves the symplectic structure almost surely and this property could be inherited by symplectic Runge--Kutta methods, which are implicit methods in general. If the vector fields belong to $Lip^γ$, we obtain the solvability of Runge--Kutta methods and the pathwise convergence rates. For linear and skew symmetric vector fields, we focus on the midpoint scheme to give corresponding results. Numerical experiments verify our theoretical analysis.

description: Model initialization is a key process of climate predictions using dynamical models. In this study, the authors evaluated the performances of two distinct initialization approaches—anomaly and full-field initializations—in ENSO predictions conducted using the IAP-DecPreS near-term climate prediction system developed by the Institute of Atmospheric Physics (IAP). IAP-DecPreS is composed of the FGOALS-s2 coupled general circulation model and a newly developed ocean data assimilation scheme called ‘ensemble optimal interpolation-incremental analysis update’ (EnOI-IAU). It was found that, for IAP-DecPreS, the hindcast runs using the anomaly initialization have higher predictive skills for both conventional ENSO and El Niño Modoki, as compared to using the full-field initialization. The anomaly hindcasts can predict super El Niño/La Nina 10 months in advance and have good skill for most moderate and weak ENSO events about 4–7 months in advance. The predictive skill of the anomaly hindcasts for El Niño Modoki is close to that for conventional ENSO. On the other hand, the anomaly hindcasts at 1- and 4-month lead time can reproduce the major features of large-scale patterns of sea surface temperature, precipitation and atmospheric circulation anomalies during conventional ENSO and El Niño Modoki winter.
Emergent Spacetime and Cosmic Inflation

description: We present a novel background-independent framework for cosmic inflation, starting with a matrix model. In this framework, inflation is portrayed as a dynamic process responsible for the generation of both space and time. This stands in contrast to conventional inflation, which is characterized as a mere (exponential) expansion of an already existing spacetime, driven by the vacuum energy associated with an inflaton field. We observe that the cosmic inflation is triggered by the condensate of Planck energy into vacuum and responsible for the dynamical emergence of spacetime. The emergent spacetime picture admits a background-independent formulation so that the inflation is described by a conformal Hamiltonian system which requires neither an inflaton field nor an ad hoc inflation potential. This implies that the emergent spacetime may incapacitate all the rationales to introduce the multiverse hypothesis.

description: We derive the fundamental thermodynamic equation for Fermi-Dirac and Bose-Einstein quantum gases, which contains the first order contribution due to the quantum nature of the gas particles. Then, we analyze the fundamental equation in the context of geometrothermodynamics. Although the corresponding Hamiltonian does not contain a potential, indicating the lack of classical thermodynamic interaction, we show that the curvature of the equilibrium space is non-zero and can be interpreted as a measure of the effective quantum interaction between the gas particles. In the limiting case of a classical Boltzmann gas, we show that the equilibrium space becomes flat, as expected from the physical viewpoint. In addition, we derive a thermodynamic fundamental equation for the Bose-Einstein condensation and, using the Ehrenfest scheme, we show that it can be considered as a first order phase transition which in the equilibrium space corresponds to a curvature singularity. This result indicates that the curvature of the equilibrium space can be used to measure in an invariant way the thermodynamic interaction in classical and quantum ideal gases.

Climate change adaptation and development aid: emerging challenges and opportunities
Creators: name: Ireland, Philip Edward
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Adaptation to anthropogenic climate change has emerged as a key focus of developmentaid. Current financing commitments indicate that there will be tens of billions of dollars infunding each year for adaptation in the developing world, most of which will be channelledthrough the development sector including non-governmental organisations, multilateraland bilateral development agencies. However, in light of the many serious critiques ofdevelopment aid over the past five decades, there are pressing questions around how theseadaptation efforts of the development sector in the developing world can be effective,appropriate and sustainable. This thesis engages with these questions by investigating how adaptation is beingconceptualised and utilised by different actors associated with the development sector. Theinvestigation draws upon extensive primary and secondary data, collected with a range ofqualitative research techniques, at local, national and international sites. These includeexploratory literature reviews, semi-structured interviews, participant observation andfocus groups. This thesis draws together a number of different papers that investigateadaptation and the development sector to identify some of the challenges and opportunitiesfor the planning and implementation of adaptation. This thesis calls for rethinking of how the subject of adaptation is being engaged by thedevelopment sector. The research shows that adaptation is being conceptualised in manydivergent ways and that there is a need for clearer and commonly understood boundariesin its meaning. It also demonstrates that development actors are utilising differentconceptualisations to support particular approaches to development aid that are guided bypre-existing assumptions, such as the need for economic growth. This thesis also drawsupon research from local community sites in Nepal and Bangladesh to argue that existingperceptions and practices of communities, including collective action, should be keyconsiderations in the planning and implementation of adaptation processes. The findings ofthe papers in this thesis come together to provide guidance for the development sector bysuggesting that approaches to adaptation should not be bedded in long held assumptions ofhow development aid should happen. Rather, adaptation needs to be approachedcautiously, and in a way that supports the diverse practices of local communities as theyreact in their own particular ways to the threat of climate change.
Gibbs measures over locally tree-like graphs and percolative entropy over infinite regular trees

description: Consider a statistical physical model on the $d$-regular infinite tree $T_{d}$ described by a set of interactions $Φ$. Let $\{G_{n}\}$ be a sequence of finite graphs with vertex sets $V_n$ that locally converge to $T_{d}$. From $Φ$ one can construct a sequence of corresponding models on the graphs $G_n$. Let $\{μ_n\}$ be the resulting Gibbs measures. Here we assume that $\{μ_{n}\}$ converges to some limiting Gibbs measure $μ$ on $T_{d}$ in the local weak$^*$ sense, and study the consequences of this convergence for the specific entropies $|V_n|^{-1}H(μ_n)$. We show that the limit supremum of $|V_n|^{-1}H(μ_n)$ is bounded above by the \emph{percolative entropy} $H_{perc}(μ)$, a function of $μ$ itself, and that $|V_n|^{-1}H(μ_n)$ actually converges to $H_{perc}(μ)$ in case $Φ$ exhibits strong spatial mixing on $T_d$. We discuss a few examples of well-known models for which the latter result holds in the high temperature regime.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We use numerical continuation and bifurcation techniques in a boundary value setting to follow Lyapunov families of periodic orbits. These arise from the polygonal system of $n$ bodies in a rotating frame of reference. When the frequency of a Lyapunov orbit and the frequency of the rotating frame have a rational relationship then the orbit is also periodic in the inertial frame. We prove that a dense set of Lyapunov orbits, with frequencies satisfying a diophantine equation, correspond to choreographies. We present a sample of the many choreographies that we have determined numerically along the Lyapunov families and along bifurcating families, namely for the cases $n=4,~6,~7,~8$, and $9$. We also present numerical results for the case where there is a central body that affects the choreography, but that does not participate in it. Animations of the families and the choreographies can be seen at the link: http://mym.iimas.unam.mx/renato/choreographies/index.html

Also, we consider Hecke operators on the space of quantum modular forms and construct new quantum modular forms.

description: South American giant fossil rodents represent a notable example of an extreme evolutionary trend towards size differentiation among caviomorph lineages. Although spectacular, fossil remains of these animals are uncommon and usually highly incomplete. We here describe fully grown adult and juvenile fossil specimens from the rodent family Dinomyidae Alston, 1876, collected from the same location, lithostratigraphical formation and fossiliferous horizon: the coast of the Río de la Plata of southern Uruguay in pelitic sediments assigned to the late Miocene Camacho Formation. The adult remains consist of an almost complete skull with partial jaw and represent the first published description of associated craneo-mandibular remains of a giant rodent within the subfamily Eumegamyinae. The juvenile specimen is the first to be recognized as such for the entire subfamily, and consists of a complete mandible and a right calcaneus. Based on the homologies observed in the configuration of the teeth, the new specimens are assigned to Isostylomys laurillardi Kraglievich, 1926, thus demonstrating that the general morphology of the teeth (including the binding pattern) of Eumegamyinae remained unchanged throughout most of their growth. The dental ontogeny of large-sized rodents casts doubt on the validity of the subfamily Gyriabrinae, which may be composed of juveniles of different taxa within other subfamilies of Dinomyidae.
Beta-decay properties of neutron-rich rare-earth isotopes

description: In this paper, beta-decay properties of even-even neutron-rich isotopes in the rare-earth mass region are studied within a microscopic theoretical approach based on a proton-neutron quasiparticle random-phase approximation. The underlying mean field is constructed selfconsistently from a deformed Hartree-Fock calculation with Skyrme interactions and pairing correlations to which particle-hole and particle-particle residual interactions are added. Nuclei in this mass region participate in the astrophysical rapid neutron capture process and are directly involved in the generation of the rare-earth peak in the isotopic abundance pattern centered at A=160. The energy distributions of the Gamow-Teller strength as well as the beta-decay half-lives and the beta-delayed neutron-emission probabilities are discussed and compared with the available experimental information and with calculations based on different approaches.

description: The current cosmological model ($Λ$CDM) with the underlying FLRW metric relies on the assumption of local isotropy, hence homogeneity of the Universe. Difficulties arise when one attempts to justify this model as an average description of the Universe from first principles of general relativity, since in general, the Einstein tensor built from the averaged metric is not equal to the averaged stress--energy tensor. In this context, the discrepancy between these quantities is called "cosmological backreaction" and has been the subject of scientific debate among cosmologists and relativists for more than $20$ years. Here we present one of the methods to tackle this problem, i.e. averaging the scalar parts of the Einstein equations, together with its application, the cosmological mass function of galaxy clusters.

description: Although fossils of Trionychidae are found as far back as the Early Cretaceous, their evolutionary history, including the origin of the crown clade, is poorly understood. Here, we use a microCT scan of the skull of ‘Trionyx’ kyrgyzensis from the late Early Cretaceous (Albian) of Kyrgyzstan as the basis for a thorough redescription of the cranial morphology of this species. New information includes the pattern of cranial circulation, which is comparable to all extant trionychids. A unique combination of cranial and postcranial characters of ‘Trionyx’ kyrgyzensis allows us to establish for it a new genus Petrochelys gen. nov. The data regarding Petrochelys kyrgyzensis are incorporated into a phylogenetic analysis. When Petrochelys kyrgyzensis is analysed without including additional, extinct taxa, it is placed in a highly derived position within the extant Nilssonia. However, the addition of five Cretaceous–Palaeogene taxa breaks up hypothesized long branches and results in more basal positions for Petrochelys kyrgyzensis within recovered trees. All results support the hypothesis that Petrochelys kyrgyzensis is a crown trionychid and a member of Trionychinae. Our findings highlight the importance of including multiple extinct taxa in phylogenetic analyses prior to using any of those taxa as calibration points in divergence dating estimates. http://zoobank.org/urn:lsid:zoobank.org:pub:592B98BF-87DF-48A8-8AA2-543AAD21FC95
'A constant disparity': an anthropological investigation into Body Integrity Identity Disorder
Creators: name: Ricciuti, Josephine Rani
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Body Integrity Identity Disorder (BIID) is a contested neurological condition, which causes individuals to feel they have an 'incorrectly abled embodiment' (Davis, 2014) resulting in feelings of disconnection from and discomfort with their own bodies. To alleviate this disparity, many seek out amputation or other radical surgery to treat what feels like an intrusive limb or sense, at great risk to themselves. BIID is heavily stigmatised and largely understudied as a condition, gaining notoriety primarily through sensationalist media reports and commentaries. Highly publicised cases of BIID have resulted in public debates about the ethics of elective surgery and the legitimacy of illness experiences, but the perspectives of people with BIID are often discounted or not considered fully, allowing misconceptions to develop. This thesis presents qualitative data collected from email-based interviews and observations of internet forums, focusing on understanding lived experiences and explanatory models. This thesis demonstrates the importance of social support and disclosure in the management of BIID symptoms, and investigates these close relationships further. This thesis ultimately aims to contribute to the demystification of BIID, aligning with the goals of emerging phenomenological literature in the field of disability impairment and chronic illness studies in anthropology. This thesis demonstrates that the experience of BIID is one that is deeply embodied, and that perceivably deviant behaviours are attempts to achieve a sense of normality and wholeness.

description: In [MT2] the Vafa-Witten theory of complex projective surfaces is lifted to oriented $\mathbb C^*$-equivariant cohomology theories. Here we study the K-theoretic refinement. It gives rational functions in $t^{1/2}$ invariant under $t^{1/2}\leftrightarrow t^{-1/2}$ which specialise to numerical Vafa-Witten invariants at $t=1$. On the "instanton branch" the invariants give the virtual $χ_{-t}^{}$-genus refinement of Göttsche-Kool. Applying modularity to their calculations gives predictions for the contribution of the "monopole branch". We calculate some cases and find perfect agreement. We also do calculations on K3 surfaces, finding Jacobi forms refining the usual modular forms, proving a conjecture of Göttsche-Kool. We determine the K-theoretic virtual classes of degeneracy loci using Eagon-Northcott complexes, and show they calculate refined Vafa-Witten invariants. Using this Laarakker [Laa] proves universality results for the invariants.

description: Records of Cenozoic tropical bryozoan faunas are sparse, particularly from Africa. Here we describe a previously unknown bryozoan ‘sand fauna’ from a drill core across the Eocene–Oligocene boundary from a hemipelagic clay succession in Tanzania. Although low in diversity, this well-preserved fauna includes four cheilostome species, all new to science: Heteractis tanzaniensis sp. nov., Bragella pseudofedora gen. et sp. nov., Lacrimula kilwaensis sp. nov. and L. crassa sp. nov. The four species vary in mineralogy, with H. tanzaniensis having an entirely aragonitic skeleton, B. pseudofedora being bimineralic and the two species of Lacrimula calcitic. These species have either free-living ‘lunulitiform’ (H. tanzaniensis) or rooted ‘conescharelliniform’ (B. pseudofedora, L. kilwaensis and L. crassa) colonies adapted to life on a soft, unstable seafloor. The peak occurrence of bryozoans in the core coincides with the Eocene–Oligocene Glacial Maximum (EOGM), characterized by global environmental change from a greenhouse to an icehouse world, sea-level fall, cooling of the oceans and changes in water circulation that may have led to enhanced nutrient levels favourable to bryozoans both in Tanzania and elsewhere. http://zoobank.org/urn:lsid:zoobank.org:pub:6E49FB4A-EB50-4BCE-9D3D-B139CB5D4C5A

description: We point out a misleading treatment in a recent paper published in this Journal [J. Math. Phys. (2016) 57, 082105] concerning solutions for the two-dimensional Dirac-Weyl equation with a q-deformed pseudoscalar magnetic barrier. The authors misunderstood the full meaning of the potential and made erroneous calculations, this fact jeopardizes the main results in this system.

description: In these lecture notes we give an introduction to the kinetic equation approach to pair production form the vacuum in strong, time-dependent external fields (dynamical Schwinger process). We first give a derivation of the kinetic equation with the source term for the case of fermions starting from the Dirac equation and for bosons from the Klein-Gordon equation. In a second part we discuss the application of the approach to the situation of external field pulses as single-sheeted functions of time (like the Sauter-pulse) and as multi- sheeted functions approximating the situation in the focal point of counter-propagating laser beams. Special emphasis is on the discussion of the time evolution of the system that exhibits the characteristics of a field-induced phase transition for which we discuss the behaviour of the entropy and particle density of the system. We give an outlook to applications of the approach in describing particle production in strong fields formed in particle and nuclear collisions.

description: Modern lightweight dual-arm robots bring the physical capabilities to quickly take over tasks at typical industrial workplaces designed for workers. In times of mass-customization, low setup times including the instructing/specifying of new tasks are crucial to stay competitive. We propose a constraint programming approach to simultaneous task allocation and motion scheduling for such industrial manipulation and assembly tasks. The proposed approach covers dual-arm and even multi-arm robots as well as connected machines. The key concept are Ordered Visiting Constraints, a descriptive and extensible model to specify such tasks with their spatiotemporal requirements and task-specific combinatorial or ordering constraints. Our solver integrates such task models and robot motion models into constraint optimization problems and solves them efficiently using various heuristics to produce makespan-optimized robot programs. The proposed task model is robot independent and thus can easily be deployed to other robotic platforms. Flexibility and portability of our proposed model is validated through several experiments on different simulated robot platforms. We benchmarked our search strategy against a general-purpose heuristic. For large manipulation tasks with 200 objects, our solver implemented using Google's Operations Research tools and ROS requires less than a minute to compute usable plans.

Order-unity argument for structure-generated "extra" expansion

description: Self-consistent treatment of cosmological structure formation and expansion within the context of classical general relativity may lead to "extra" expansion above that expected in a structureless universe. We argue that in comparison to an early-epoch, extrapolated Einstein-de Sitter model, about 10-15% "extra" expansion is sufficient at the present to render superfluous the "dark energy" 68% contribution to the energy density budget, and that this is observationally realistic.

description: We consider the Cahn-Hilliard equation on manifolds with conical singularities. For appropriate initial data, we show that the solution exists in the maximal $L^q$-regularity space for all times and becomes instantaneously smooth in space and time, where the maximal $L^q$-regularity is obtained in the sense of Mellin-Sobolev spaces. Moreover, we provide precise information concerning the asymptotic behavior of the solution close to the conical tips in terms of the local geometry.

The interpretation of logical connectors by monolingual and bilingual children

Subjects: Other education not elsewhere classified

description: This dissertation investigated the scope relations assigned by English-, German- and Turkish-speaking monolingual and bilingual children. Across languages, disjunction is assigned different interpretations in negative sentences and in sentences with the temporal term before. For instance, the English (and German) sentence A did not eat B or C licenses the ‘conjunctive’ interpretation that A did not eat B and did not eat C. On this interpretation, negation takes scope over disjunction (NOT > OR). In adult Turkish, if the disjunction phrase is marked with accusative case, then disjunction takes scope over negation (OR > NEG), yielding the ‘disjunctive’ interpretation that A either did not eat B or did not eat C. Scope relations between disjunction and the temporal term before also differ across languages. In English (and German), the sentence A reached the finish line before B or C requires A to reach the finish line before both B and C. In Turkish, the corresponding sentences are true in this circumstance, and also in other circumstances. Adopting a learnability principle called the Semantic Subset Principle, the experimental hypothesis was that children, across languages, would initially adopt the strongest (subset) interpretation of both kinds of sentences, in order to guarantee language learnability regardless of the scope assignments preferred by adults. These predictions were evaluated in three experiments using the Truth Value Judgment Task, testing monolingual children acquiring German, English, and Turkish, and Turkish-English bilingual children. On the proposed account, both groups of Turkish-speaking children were expected to initially assign interpretations that do not match those of the adults, whereas the interpretations assigned by German- and English-speaking children were expected to match those of adults. As predicted, both monolingual and bilingual children were found to initially assign a strong subset reading to disjunction in all three languages, both when disjunction appeared in the scope of negation and when it appeared in the scope of the temporal term before. This meant that the interpretations assigned by Turkish-speaking children differed from those of adults.

description: Hydrogen-rich compounds are important for understanding the dissociation of dense molecular hydrogen, as well as searching for room temperature Bardeen-Cooper-Schrieffer (BCS) superconductors. A recent high pressure experiment reported the successful synthesis of novel insulating lithium polyhydrides when above 130 GPa. However, the results are in sharp contrast to previous theoretical prediction by PBE functional that around this pressure range all lithium polyhydrides (LiHn (n = 2-8)) should be metallic. In order to address this discrepancy, we perform unbiased structure search with first principles calculation by including the van der Waals interaction that was ignored in previous prediction to predict the high pressure stable structures of LiHn (n = 2-11, 13) up to 200 GPa. We reproduce the previously predicted structures, and further find novel compositions that adopt more stable structures. The van der Waals functional (vdW-DF) significantly alters the relative stability of lithium polyhydrides, and predicts that the stable stoichiometries for the ground-state should be LiH2 and LiH9 at 130-170 GPa, and LiH2, LiH8 and LiH10 at 180-200 GPa. Accurate electronic structure calculation with GW approximation indicates that LiH, LiH2, LiH7, and LiH9 are insulative up to at least 208 GPa, and all other lithium polyhydrides are metallic. The calculated vibron frequencies of these insulating phases are also in accordance with the experimental infrared (IR) data. This reconciliation with the experimental observation suggests that LiH2, LiH7, and LiH9 are the possible candidates for lithium polyhydrides synthesized in that experiment. Our results reinstate the credibility of density functional theory in description H-rich compounds, and demonstrate the importance of considering van der Waals interaction in this class of materials.

The fractional porous medium equation on manifolds with conical singularities II

description: This is the second of a series of two papers which studies the fractional porous medium equation, $\partial_t u +(-Δ)^σ(|u|^{m-1}u )=0 $ with $m>0$ and $σ\in (0,1]$, posed on a Riemannian manifold with isolated conical singularities. The first aim of the article is to derive some useful properties for the Mellin-Sobolev spaces including the Rellich-Kondrachov Theorem and Sobolev-Poincaré, Nash and Super Poincaré type inequalities. The second part of the article is devoted to the study the Markovian extensions of the conical Laplacian operator and its fractional powers. Then based on the obtained results, we establish existence and uniqueness of a global strong solution for $L_\infty-$initial data and all $m>0$. We further investigate a number of properties of the solutions, including comparison principle, $L_p-$contraction and conservation of mass. Our approach is quite general and thus is applicable to a variety of similar problems on manifolds with more general singularities.

description: This paper deals with fractional boundary value problems involving the Hilfer fractional differential operator of order $1 < α\leq 2$ and type $0 \leq β\leq 1$. We derive the corresponding Lyapunov-type inequalities for two prominent classes of Hilfer fractional boundary value problems (HFBVPs) involving separated and anti-periodic boundary conditions. For this purpose, we construct the associated Green's functions and deduce their important properties.
