description: Tra ottobre e dicembre 2017, Edoardo Boria è stato animatore di un ciclo
di seminari organizzati presso la Società Geografica Italiana dal titolo
Nuovi orizzonti del pensiero geografico: la geopolitica oggi. Occasione di questi incontri è stata la realizzazione del documentario “Cos’è Geopolitica” che ha avuto tra l’altro il pregio di evidenziare come l’uso degli strumenti audiovisivi possa contribuire efficacemente alla divulgazione del pensiero geografico, assolvendo dunque al duplice compito di sostegno alla didattica e alla divulgazione scientifica, producendo al contempo nuove modalità narrative del sapere geografico rileggendo in chiave spaziale la dimensione politica della società.
Questo breve dialogo nasce così da una duplice esigenza. Da un lato, nei
termini cioè che più direttamente competono agli obiettivi che questa rubrica si prefigge, evidenziare il nesso tra comunicazione del sapere geografico e profondità della riflessione teorico-metodologica sulla spazialità e la territorialità; dall’altro proporre, per quanto qui possibile, esempi di pratiche della didattica innovanti.

description: We prove that a K3 surface with an automorphism acting on the global $2$-forms by a primitive $m$-th root of unity, $m \neq 1,2,3,4,6$, does not degenerate (assuming the existence of the so-called Kulikov models). A key result used to prove this is the rationality of the actions of automorphisms on the graded quotients of the weight filtration of the $l$-adic cohomology groups of the surface.

description: This paper studies two perfectly conducting parallel plates in the weak gravitational field on the surface of the Earth. Since the appropriate line element, to first order in the constant gravity acceleration g, is precisely of the Rindler type, we can exploit the formalism for studying Feynman Green functions in Rindler spacetime. Our analysis does not reduce the electromagnetic potential to the transverse part before quantization. It is instead fully covariant and well suited for obtaining all components of the regularized and renormalized energy-momentum tensor to arbitrary order in the gravity acceleration g. The general structure of the calculation is therefore elucidated, and the components of the Maxwell energy-momentum tensor are evaluated up to second order in g, improving a previous analysis by the authors and correcting their old first-order formula for the Casimir energy.

Subjects: subject: Astrophysics (astro-ph)

description: The IceCube neutrino detector is a cubic kilometer TeV to PeV neutrino detector under construction at the geographic South Pole. The dominant population of neutrinos detected in IceCube is due to meson decay in cosmic-ray air showers. These atmospheric neutrinos are relatively well-understood and serve as a calibration and verification tool for the new detector. In 2006, the detector was approximately 10% completed, and we report on data acquired from the detector in this configuration. We observe an atmospheric neutrino signal consistent with expectations, demonstrating that the IceCube detector is capable of identifying neutrino events. In the first 137.4 days of livetime, 234 neutrino candidates were selected with an expectation of 211 +/- 76.1(syst.) +/- 14.5(stat.) events from atmospheric neutrinos.
title: A loop flow analysis in the power transmission grid using Power Flow Colouring and Generation Shift Key optimisation

subject: power flow colouring

subject: transmission grid

description: In order to achieve the European climate targets, the use of renewable energies must be significantly expanded. The associated volatility in the generation leads to more and more congestions in the transmission grid, which have to be solved at considerable cost. In order to distribute the costs incurred among the transmission system operators (TSOs), the European Union has directed the TSOs to develop a Cost Sharing methodology. The allocation of costs is based on the polluter pays principle. This means that the originators of loop flows are identified and are responsible for bearing the associated costs. This thesis examines the impact of Generation Shift Keys (GSKs) on loop flow calculations, employing the Power Flow Colouring (PFC) method. Subsequently, this study will address the impact of these results on the cost calculation using the Core Cost Sharing method. The research compares various GSK strategies with a view to determining their impact on loop flow results for critical network elements around Austria. These include the Proportional to Generation GSK, a Unified GSK and the Dynamic GSK employed by APG. A key objective of this thesis is to develop and evaluate an Optimised GSK that minimises the loop flows and costs determined in the Core Cost Sharing method. The results demonstrate that the selection of GSK can have a significant impact on the outcomes of loop flow calculations and cost sharing, and that optimisation can result in a substantial reduction of loop flows and costs. The findings assist in enhancing grid management and also provide valuable insights into the functioning of the PFC method and for the development of future GSK methods. In conclusion, the implications for grid strategy are identified and potential avenues for further research are proposed, with a particular focus on the optimisation of GSKs under diverse grid conditions.

description: In this paper we elaborate on the translation-invariant renormalizable Phi^4 theory in 4-dimensional non-commutative space which was recently introduced by the Orsay group. By explicitly performing Feynman graph calculations at one loop and higher orders we illustrate the mechanism which overcomes the UV/IR mixing problem and ultimately leads to a renormalizable model. The obtained results show that the IR divergences are also suppressed in the massless case, which is of importance for the gauge field theoretic generalization of the scalar field model.

description: Nuove dinamiche nei Balcani verso l’UE:la gestione del più grande vigneto in Montenegro
Il contributo documenta i risultati preliminari di una ricerca ancora in corso sul
Montenegro, che, superando una storica marginalità, sta riorganizzando gli spazi
rurali in vista dell’ammissione all’UE. Tramite una lettura diacronica, si dà risalto ai cambiamenti che il Montenegro sta attuando, utilizzando una metodologia integrata, cioè discussione della letteratura più aggiornata e analisi di informazioni raccolte in situ. In particolare si esamina l’hinterland della capitale Podgorica, dove si è avuta una forte concentrazione di popolazione e servizi a discapito delle località rurali che formano il suo territorio comunale. Proprio qui, però, esperienza significativa è la gestione dell’azienda viti-vinicola Plantaže. Le dimensioni economiche, i suoi processi di vendita e di produzione rendono la Plantaže un buon esempio di rimodulazione multi-funzionale delle attività agricole, mentre la costruzione della strada del vino promuove le aree rurali marginali. L’esperienza della Plantaže è un’opportunità per l’hinterland di Podgorica, ma rappresenta anche un modello da disseminare, principalmente per il rinnovamento della tradizione enologica dei Balcani.

En particulier, il examine l’hinterland de la capitale Podgorica, où il y avait une forte concentration de la population et des services au détriment des zones rurales qui forment sa zone municipale. Ici, cependant, l’expérience significative est la gestion de la Plantaže entreprise vinicole. La taille économiques, de ses processus de vente et de production font Plantaže un bon exemple de remodelage multifonctionnelle des activités agricoles, tandis que la construction de la route du vin favorise les zones rurales marginales. L’expérience de Plantaže est une occasion pour l’hinterland de Podgorica, mais représente également un modèle de diffusion, principalement pour le renouvellement de la tradition viticole des Balkans.

description: Utilizing time-resolved Kerr rotation techniques, we have investigated the spin dynamics of a high mobility, low density two dimensional electron gas in a GaAs/Al0:35Ga0:65As heterostructure in dependence on temperature from 1.5 K to 30 K. It is found that the spin relaxation/dephasing time under a magnetic field of 0.5 T exhibits a maximum of 3.12 ns around 14 K, superimposed on an increasing background with rising temperature. The appearance of the maximum is ascribed to that at the temperature where the crossover from the degenerate to the nondegenerate regime takes place, electron-electron Coulomb scattering becomes strongest, and thus inhomogeneous precession broadening due to D'yakonov-Perel'(DP) mechanism becomes weakest. These results agree with the recent theoretical predictions [Zhou et al., PRB 75, 045305 (2007)], verifying the importance of electron-electron Coulomb scattering to electron spin relaxation/dephasing.

The inland areas of Sicily. From rural development to territorial reorganization

description: Le zone interne della Sicilia. Dallo sviluppo rurale alla riorganizzazione territoriale
La terziarizzazione dell’economia mondiale e l’espansione di grandi aree urbane, la divisione del lavoro frammentato e instabile hanno aggravato in Sicilia il contrasto tra le aree metropolitane costiere e lo spopolamento delle aree interne, storicamente caratterizzate dalla presenza di attività agricole. Gli autori di questo articolo prendono in considerazione le dinamiche demografiche delle aree interne della Sicilia in relazione ai tentativi di avviare processi di sviluppo economico, prevalentemente incentrati sulla valorizzazione delle risorse agricole. Ma, né la trasformazione del mondo rurale siciliano, né le altre sporadiche iniziative economiche sono state sufficienti a trattenere la popolazione. Le comunità locali ripongono invece molteplici speranze dell’abolizione delle province, avvenuta nel marzo 2013, che ha innescato un vivace dibattito sulle nuove forme di aggregazioni territoriali per migliorare non solo le attività produttive ma anche le attività turistiche, i servizi urbani e strategici.

Les régions intérieures de la Sicile. Du développement rural à la réorganisation territoriale
Le secteur des services de l’économie mondiale et l’expansion des grandes zones urbaines, la division du travail qui devient fragmenté et instable ont aggravé en Sicile le contraste entre les zones métropolitaines côtières et le dépeuplement des régions internes qui historiquement ont été caractérisées par la présence d’activités agricoles.
Les auteurs de cet article analysent les dynamiques démographiques des zones
internes de la Sicile en relation aux essais visant à démarrer des processus de
développement économique qui se basent essentiellement sur la mise en valeur des ressources agricoles. Mais ni la transformation de la Sicile rurale ni d’autres
initiatives économiques sporadiques ont étaient suffisantes pour retenir la
population. D’autre part les communautés locales mettent beaucoup espoirs de
l’abolition des provinces en Mars 2013 qui a suscité un vif débat sur les nouvelles formes d’agrégations territoriales dans le but de développer non seulement les activités de production, mais aussi les activités touristiques et les services urbains et stratégiques.

description: As Engineering Education Research (EER) develops as a discipline it is necessary for EER scholars to contribute to the development of learning theory rather than simply being informed by it. It has been suggested that to do this effectively will require partnerships between Engineering scholars and psychologists, education researchers, including other social scientists. The formation of such partnerships is particularly important when considering the introduction of business-related skills into engineering curriculum designed to prepare 21st Century Engineering Students for workplace challenges. In order to encourage scholars beyond Engineering to engage with EER, it is necessary to provide an introduction to the complexities of EER. With this aim in mind, this paper provides an outline review of what is considered rigorous research from an EER perspective as well as highlighting some of the core methodological traditions of EER. The paper aims to facilitate further discussion between EER scholars and researchers from other disciplines, ultimately leading to future collaboration on innovative and rigorous EER.

description: The migration of hundreds of millions of rural Chinese workers to the city has contributed substantially to China’s economic growth since the beginning of the country’s economic reform in 1978. However, this migration has also led to societal issues, including more than 60 million left-behind children. Empirical studies that seek to measure the impact of being left-behind on academic performance have led to inconsistent results, perhaps because the effects may be different for first-parent migration (migration during the first period of time in which one parent migrates) and second-parent migration (migration when the remaining parent leaves the home). Here we have examined how school performance changes before and after the second parent out-migrates. We use a panel dataset of over 5,000 students from 72 primary schools in rural China. Using a difference-in-difference approach, supported by a placebo test, we find that second-parent migration has statistically significant negative impacts on student performance. Importantly, our data provide convincing evidence that second-parent migration has a more negative impact on academic performance than first-parent migration. Our results have broad implications for China’s future economic growth and inequality.
Large magnetoresistance dips and perfect spin-valley filter induced by topological phase transitions in silicene

description: Spin-valley transport and magnetoresistance are investigated in silicene-based N/TB/N/TB/N junction where N and TB are normal silicene and topological barriers. The topological phase transitions in TB's are controlled by electric, exchange fields and circularly polarized light. As a result, we find that by applying electric and exchange fields, four groups of spin-valley currents are perfectly filtered, directly induced by topological phase transitions. Control of currents, carried by single, double and triple channels of spin-valley electrons in silicene junction, may be achievable by adjusting magnitudes of electric, exchange fields and circularly polarized light. We may identify that the key factor behind the spin-valley current filtered at the transition points may be due to zero and non-zero Chern numbers. Electrons that are allowed to transport at the transition points must obey zero-Chern number which is equivalent to zero mass and zero-Berry's curvature, while electrons with non-zero Chern number are perfectly suppressed. Very large magnetoresistance dips are found directly induced by topological phase transition points. Our study also discusses the effect of spin-valley dependent Hall conductivity at the transition points on ballistic transport and reveals the potential of silicene as a topological material for spin-valleytronics.

description: We electron-dope single crystal samples of SrTiO_3 by exposing them to Ar^+ irradiation and observe carrier mobility similar in its magnitude and temperature dependence to the carrier mobility in other electron-doped SrTiO3 systems. We find that some transport properties are time-dependent. In particular, the sheet resistance increases with time at a temperature-dependent rate, suggesting an activation barrier on the order of 1 eV. We attribute the relaxation effects to diffusion of oxygen vacancies - a process with energy barrier similar to the observed activation energy.

The influence of natural predation on the population dynamics of Pacific salmon : an experimental study
Creators: name: Jones, Michael Lewis
Publisher: name: University of British Columbia
Year: 2010

description: Predation is widely assumed to make an important contribution to the determination of year class strength in Pacific salmon. For the most part, this assumption is based on little in the way of a functional understanding of predator-prey interactions involving juvenile salmon. As a first step towards addressing this shortcoming, this thesis presents the results of a field experimental study that evaluates functionally the interaction between a predator, prickly sculpins (Cottus asper) and chum salmon fry (Oncorhynchus keta). The field research was conducted at an estuarine (Fraser estuary) and a freshwater (Rosewall Creek) site. In situ enclosures were used to ascertain the effect of prey density, prey and predator size and alternate prey on sculpin predation rates. Field and laboratory observations of predator distribution, abundance and feeding behaviour were used to complement the enclosure experiments. For the most part the experimental results were consistent with expectation. Predator search rates were far lower than expected, however; possibly due to partial spatial segregation of the predator from its prey. As well, the data did not fit a simple stochastic model of predation based on random search and encounter, suggesting that the predation process is far from random. Alternate prey strongly influenced predation on chum fry, as did predator size. Larger sculpins had greater search rates and maximum ration levels. In contrast, prey size did not appear to influence predation. The experimental results were combined with other field data to develop crude estimates of the overall impact of sculpin predation on chum fry in the two systems studied. In the Fraser estuary, the impact estimates are particularly uncertain, due to inadequate knowledge of sculpin abundance and chum fry residence times. Nevertheless, plausible estimates are high enough to be considered significant (6-81%). For Rosewall Creek, a simulation model was developed and used to explore the effect of changing fry production on sculpin predation rates. The key result was that although the model predicted compensatory mortality to occur as fry abundance increased, it was not sufficient to regulate the prey population. An additional unexpected result of the field experiments was gorging of fry by sculpins at very high prey densities. This behaviour is not predicted by conventional predation models, although it has been observed in many predator-prey systems. Two alternative models are proposed that might account for this phenomenon, one based on digestive physiology and the other on optimal foraging theory. Evidence is presented to suggest that the former is unlikely to be true, while the latter may offer a realistic generalization of conventional predation models that accounts for extrinsic restrictions on the predator's foraging behaviour.

description: METIS, the Mid-infrared ELT Imager and Spectrograph (formerly called MIDIR), is a proposed instrument for the European Extremely Large Telescope (E-ELT), currently undergoing a phase-A study. The study is carried out within the framework of the ESO-sponsored E-ELT instrumentation studies. METIS will be designed to cover the E-ELT science needs at wavelengths longward of 3um, where the thermal background requires different operating schemes. In this paper we discuss the main science drivers from which the instrument baseline has been derived. Specific emphasis has been given to observations that require very high spatial and spectral resolution, which can only be achieved with a ground-based ELT. We also discuss the challenging aspects of background suppression techniques, adaptive optics in the mid-IR, and telescope site considerations. The METIS instrument baseline includes imaging and spectroscopy at the atmospheric L, M, and N bands with a possible extension to Q band imaging. Both coronagraphy and polarimetry are also being considered. However, we note that the concept is still not yet fully consolidated. The METIS studies are being performed by an international consortium with institutes from the Netherlands, Germany, France, United Kingdom, and Belgium.

Tidally induced multipole moments of a nonrotating black hole vanish to all post-Newtonian orders
Creators: name: Poisson, Eric
Publisher: name: arXiv
Year: 2021
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The tidal Love numbers of a black hole vanish, and this is often taken to imply that the hole's tidally induced multipole moments vanish also. An obstacle to establishing a link between these statements is that the multipole moments of individual bodies are not defined in general relativity, when the bodies are subjected to a mutual gravitational interaction. In a previous publication [Phys. Rev. D 103, 064023 (2021)] I promoted the view that individual multipole moments can be defined when the mutual interaction is sufficiently weak to be described by a post-Newtonian expansion. In this view, a compact body is perceived far away as a skeletonized post-Newtonian object with a multipole structure, and the multipole moments can then be related to the body's Love numbers. I expand on this view, and demonstrate that all static, tidally induced, mass multipole moments of a nonrotating black hole vanish to all post-Newtonian orders. The proof rests on a perturbative solution to the Einstein-Maxwell equations that describes an electrically charged particle placed in the presence of a charged black hole. The gravitational attraction between particle and black hole is balanced by electrostatic repulsion, and the system is in an equilibrium state. The particle provides a tidal environment to the black hole, and the multipole moments vanish for this environment. I argue that the vanishing is robust, and applies to all slowly-varying tidal environments. The black hole's charge can be as small as desired (though not identically zero); by continuity, the multipole moments of an electrically neutral black hole will continue to vanish.

description: We construct a DGP inspired braneworld scenario where a scalar field non-minimally coupled to the induced Ricci curvature is present on the brane. First we investigate the status of gravitational potential with non-minimal coupling and observational constraints on this non-minimal model. Then we further deepen the idea of embedding of FRW cosmology in this non-minimal setup. Cosmological implications of this scenario are examined with details and the quintessence and late-time expansion of the universe within this framework are examined. Some observational constraints imposed on this non-minimal scenario are studied and relation of this model with dark radiation formalism is determined with details.

description: È un viaggio nell’Italia contemporanea quello che realizza Nicola Campiotti in Sarà un paese (2014, 77’), di cui ospitiamo in questa rubrica una stimolante riflessione. Una operazione dunque doppiamente ekfrastica quella che ci accingiamo a fare nello spirito originario che ha mosso l’ideazione della rubrica stessa e che qui rilanciamo anche in una prospettiva disciplinare: operare un esercizio di descrizione verbale per un’opera d’arte visiva rappresenta a nostro avviso uno dei passi da compiere anche in direzione di una geografia delle emozioni e delle azioni verso cui
proviamo ad orientarci.

description: The tropical Nevanlinna theory is Nevanlinna theory for tropical functions or maps over the max-plux semiring by using the approach of complex analysis. The main purpose of this paper is to study the second main theorem with tropical hypersurfaces into tropical projective spaces and give a defect relation which can be regarded as a tropical version of the Shiffman's conjecture. On the one hand, our second main theorem improves and extends the tropical Cartan's second main theorem due to Korhonen and Tohge [Advances Math. 298(2016), 693-725]. The growth of tropical holomorphic curve is also improved to $\limsup_{r\rightarrow\infty}\frac{\log T_{f}(r)}{r}=0$ (rather than just hyperorder strictly less than one) by obtaining an improvement of tropical logarithmic derivative lemma. On the other hand, we obtain a new version of tropical Nevanlinna's second main theorem which is different from the tropical Nevanlinna's second main theorem obtained by Laine and Tohge [Proc. London Math. Soc. 102(2011), 883-922]. The new version of the tropical Nevanlinna's second main theorem implies an interesting defect relation that $δ_{f}(a)=0$ holds for a nonconstant tropical meromorphic function $f$ with $\limsup_{r\rightarrow\infty}\frac{\log T_{f}(r)}{r}=0$ and any $a\in\mathbb{R}$ such that $f\oplus a\not\equiv a.$

description: With the availability of multi-object spectrometers and the designing \& running of some large scale sky surveys, we are obtaining massive spectra. Therefore, it becomes more and more important to deal with the massive spectral data efficiently and accurately. This work investigated the classification problem of stellar spectra under the assumption that there is no perfect absolute flux calibration, for example, the spectra from Guoshoujing Telescope (the Large Sky Area Multi-Object Fiber Spectroscopic Telescope, LAMOST). The proposed scheme consists of the following two procedures: Firstly, a spectrum is normalized based on a 17th polynomial fitting; Secondly, a random forest (RF) is utilized to classifying the stellar spectra. The experiments on four stellar spectral libraries show that RF has a good classification performance. This work also studied the spectral feature evaluation problem based on RF. The evaluation is helpful in understanding the results of the proposed stellar classification scheme and exploring its potential improvements in future.

Sarà un paese: come racconteresti l’Italia ad un bambino? Appunti a margine di un viaggio che è diventato un film

description: Cosa cominciare a raccontare a dei bambini dell’Italia? E, d’altra parte, perché i miei amici se ne andavano?
Su queste due domande poggia l’intero progetto di Sarà un Paese, un documentario di 72 minuti, scelto dall’Unicef per festeggiare il 25esimo anniversario della Convenzione sui diritti sull’infanzia e l’adolescenza.
L’idea è stata quella di compiere un viaggio per realizzare un film documentario
che affrontasse e raccogliesse una manciata di temi, una sorta di breviario, di compendio delle cose a mio parere imprescindibili da raccontare e condividere con un bambino. Con quale obiettivo? Con il solo scopo di immaginare insieme un paese più civile di questo.

Per organizzare o richiedere una proiezione del film scrivere all’indirizzo distribuzione.indmr@gmail.com o visitare il sito www.saraunpaese.it.

description: We report the experimental observation of strong two-color optical nonlinearity in an ultracold gas of $^{85}\mathrm{Rb}$-$^{87}\mathrm{Rb}$ atom mixture. By simultaneously coupling two probe transitions of $^{85}$Rb and $^{87}$Rb atoms to Rydberg states in electromagnetically induced transparency (EIT) configurations, we observe significant suppression of the transparency resonance for one probe field when the second probe field is detuned at $\sim1~\mathrm{GHz}$ and hitting the EIT resonance of the other isotope. Such a cross-absorption modulation to the beam propagation dynamics can be described by two coupled nonlinear wave equations we develope. We further demonstrate that the two-color optical nonlinearity can be tuned by varying the density ratio of different atomic isotopes, which highlights its potential for exploring strongly interacting multi-component fluids of light.

description: The Price equation describes the change in populations. Change concerns some value, such as biological fitness, information or physical work. The Price equation reveals universal aspects for the nature of change, independently of the meaning ascribed to values. By understanding those universal aspects, we can see more clearly why fundamental mathematical results in different disciplines often share a common form. We can also interpret more clearly the meaning of key results within each discipline. For example, the mathematics of natural selection in biology has a form closely related to information theory and physical entropy. Does that mean that natural selection is about information or entropy? Or do natural selection, information and entropy arise as interpretations of a common underlying abstraction? The Price equation suggests the latter. The Price equation achieves its abstract generality by partitioning change into two terms. The first term naturally associates with the direct forces that cause change. The second term naturally associates with the changing frame of reference. In the Price equation's canonical form, total change remains zero because the conservation of total probability requires that all probabilities invariantly sum to one. Much of the shared common form for the mathematics of different disciplines may arise from that seemingly trivial invariance of total probability, which leads to the partitioning of total change into equal and opposite components of the direct forces and the changing frame of reference.

description: Ultracold LiCs molecules in the absolute ground state X$^1Σ^+$, v"=0, J"=0 are formed via a single photo-association step starting from laser-cooled atoms. The selective production of v"=0, J"=2 molecules with a 50-fold higher rate is also demonstrated. The rotational and vibrational state of the ground state molecules is determined in a setup combining depletion spectroscopy with resonant-enhanced multi-photon ionization time-of-flight spectroscopy. Using the determined production rate of up to 5x10^3 molecules/s, we describe a simple scheme which can provide large samples of externally and internally cold dipolar molecules.

description: In $L_2(\mathbb{R}^d;\mathbb{C}^n)$, we consider a matrix elliptic second order differential operator $B_\varepsilon >0$. Coefficients of the operator $B_\varepsilon$ are periodic with respect to some lattice in $\mathbb{R}^d$ and depend on $\mathbf{x}/\varepsilon$. We study the quantitative homogenization for the solutions of the hyperbolic system $\partial _t^2\mathbf{u}_\varepsilon =-B_\varepsilon\mathbf{u}_\varepsilon$. In operator terms, we are interested in approximations of the operators $\cos (tB_\varepsilon ^{1/2})$ and $B_\varepsilon ^{-1/2}\sin (tB_\varepsilon ^{1/2})$ in suitable operator norms. Approximations for the resolvent $B_\varepsilon ^{-1}$ have been already obtained by T.~A.~Suslina. So, we rewrite hyperbolic equation as a system for the vector with components $\mathbf{u}_\varepsilon $ and $\partial _t\mathbf{u}_\varepsilon$, and consider the corresponding unitary group. For this group, we adapt the proof of the Trotter-Kato theorem by introduction of some correction term and derive hyperbolic results from elliptic ones.
