seminar on January 11, 2023 - Giulia Di Nunno
by Emanuela Rosazza Gianin 22 Dec '22

22 Dec '22

Dear all, you are all invited to participate to the following seminar on *Wednesday 11th of January 2023 at 16:30* in Aula Seminari 4026 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 4th floor): Speaker: *Giulia Di Nunno* (University of Oslo) Titolo: *Sandwiched Volterra volatility models and hedging* Abstract: We present the Sandwiched Volterra Volatility (SVV) model and we discuss some of its characteristic properties. We then move to consider hedging and consider the explicit computation of quadratic hedging strategies. While the theoretical solution is well-known in terms of the non-anticipating derivative for all square integrable claims, the fact that these models are typically non-Markovian provides a concrete difficulty in the direct computation of conditional expectations at the core of the explicit hedging strategy. To overcome this difficulty, we propose a Markovian approximation of the model which stems from an adequate approximation of the kernel in the Volterra noise. We show some numerical simulations performed with different methods. Best wishes, Emanuela ****************************************** Emanuela Rosazza Gianin Department of Statistics and quantitative methods University of Milano-Bicocca Via Bicocca degli Arcimboldi, 8 20126 Milano - Italy Phone (0039) 02 64483208 e-mail: emanuela.rosazza1(a)unimib.it ******************************************

Padova Seminars in Probability and Finance - Simone Floreani (University of Oxford)
by Alberto Chiarini 16 Dec '22

16 Dec '22

Dear Colleagues, We would like to invite you to the "Padova Seminars in Probability and Finance seminar" that will take place on December 21st at 11.00 in Padova in room 2AB45 at the department of Mathematics “Tullio Levi-Civita". The seminar will be held in person and online via the Zoom platform. _____________________________________________________ Speaker: Simone Floreani (University of Oxford) Title: Hydrodynamics for the partial exclusion process in random environment via stochastic duality Date and time: Wednesday, DECEMBER 21st at 11.00 Place: room 2AB45 at the Department of Mathematics, University of Padova Zoom link: https://unipd.zoom.us/j/88295505400 available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: In this talk, I present a partial exclusion process in random environment, a system of random walks where the random environment is obtained by assigning a maximal occupancy to each site of the Euclidean lattice. This maximal occupancy is allowed to randomly vary among sites, and partial exclusion occurs. After recalling some results on the Bouchaud's trap model, I will show that, when assuming that the maximal occupancies are heavy tailed and i.i.d., the hydrodynamic limit of the particle system is the fractional-kinetics equation. The strategy of the proof is based on stochastic duality, a useful tool in probability theory which allows to study a Markov process (the one that interests you) via another one, called dual process, which is hopefully simpler. In the final part of the talk, I will focus on how some duality relations can be obtained in a more general framework.

More details: 21st of December 2022, h 16:30, Aula seminari 4026, Building U7, 4th floor Department of Statistics and Quantitative Methods, University of Milano-Bicocca Webex Link: https://unimib.webex.com/unimib/j.php?MTID=mcd5a40a675fd6136e8c3be8a8ead4143 Join by meeting number Meeting number (access code): 2742 148 3807 Meeting password: x3765HJJdRf (93765455 from phones) Speaker: Salvatore Scognamiglio Title: ''Deep learning models for longevity risk'' Abstract: In recent decades, the mortality rates of most developed countries have been gradually declining due to improvements in public health, medical advances, lifestyle changes and government regulation. Although longevity improvement is an obvious benefit for society, it could also represent a risk for governments and insurance companies. Indeed, they could get in financial trouble if they do not adequately consider these longevity improvements for retirement planning and life insurance product pricing. The risk that future mortality and life expectancy outcomes turn out differently than expected is typically called longevity risk, and its management requires stochastic mortality projection models. We introduce a neural network (NN) to fit the Lee-Carter models and some of its extensions on multiple populations. The NN architecture is specifically designed to calibrate each individual model using all available information instead of using a population-specific subset of data as in the traditional estimation schemes. An extensive set of numerical experiments performed on all the countries of the Human Mortality Database shows the effectiveness of our approach. In particular, the resulting parameter estimates appear smooth and less sensitive to the random fluctuations often present in the mortality rates’ data, especially for low-population countries. In addition, the forecasting performance results significantly improved as well.

Annuncio Seminario Sapienza - Giacomo Greco
by Lorenzo Taggi 14 Dec '22

14 Dec '22

Martedì 20 Dicembre, ore 14:00, Sapienza Università di Roma, Dipartimento di Matematica, Sala di Consiglio *Speaker: *Giacomo Greco (Eindhoven University of Technology TU/e) *Titolo:* Travelling through turnpikes in the Kinetic Schrödinger Problem *Abstract:* The Schrödinger problem consists in finding the most likely evolution of a system of i.i.d. particles, conditionally on their initial and final configurations. In the last decade this problem has become more and more popular, thanks to its connections with stochastic optimal control theory and optimal transport. In this talk we are going to introduce a Schrödinger problem where the particles follow an (underdamped) Langevin dynamics (i.e. their density satisfies the kinetic Fokker-Planck equation) and where we are given only a partial observation of the initial and final configurations. Then, we will investigate the long-time behaviour of this kinetic system, proving that its most likely evolution is exactly the one that spends most of the time exponentially close to the equilibrium configuration (this property is commonly known in stochastic control theory as the turnpike property).

Seminar by A. Awerkin in Padova (Friday 16.12.2022)
by Giorgia Callegaro 13 Dec '22

13 Dec '22

Dear all, you're invited to the next seminar in Probability and Finance, that will take place on Friday 16th December, at 15.30, in hybrid mode at the Mathematics Department of the University of Padova. More details: * *Speaker*: *Almendra Awerkin* (Università di Brescia) * *Date and time*: 16th December 2022, 3.30 pm * *Room (Torre Archimede)*: room 702 * *Zoom link*: please find it at https://www.math.unipd.it/~bianchi/seminari/ * *Title*: *Optimal investment and fair sharing rules of the incentives for renewable energy communities * * *Abstract*: In order to face climate and energy objectives, as reduction of GHG emission and energy independency, countries start to promote sustainable energy plans. In the research for solutions to achieve such goals, Renewable Energy Communities (REC) start to play an important role. A REC is defined as a cooperative, non-profit organization of final customers, which can involve different stakeholders, such as municipalities, local societies, public and private companies, with the purpose of self-producing and self-consuming energy from renewable sources. Recently, the Italian government introduced an incentive tariff for REC. The special feature of this tariff is that it rewards the shared energy from the installation of new renewable sources. Shared energy is defined as the demand of the community which is satisfied by the self-production of energy. In this context, two relevant problems have to be solved: the optimal investment in new technologies and a fair division of the incentive among the community members. In this talk we address this problem by modeling an energy community as a static leader follower problem, where the leader, which can be understood as the administrator or coordinator of the REC, decides the percentage of the incentive that correspond to each member of the community, while the followers, represented by the members of the community, decide how much initially invest in new renewable energy production. We identified the optimal division of the incentive (leader) with a Nash bargaining solution. Additionally, we supposed a competitive game between the community members (followers) and we identified the initial optimal investment solution with a Nash equilibrium. We finish the talk by presenting some extension of our model, partial results and work in progress related to the optimal investment and management of energy communities.

LUISS Math Seminars: Katia Colaneri, Thursday 15 December
by Alessandro Calvia 13 Dec '22

13 Dec '22

Dear all, I am pleased to announce the next seminar in the LUISS math seminars series. Speaker: Katia Colaneri, Università di Roma Tor Vergata. Title: Some Optimisation Problems in Insurance with a Terminal Distribution Constraint. Abstract: We study two optimisation settings for an insurance company, under the constraint that the terminal surplus at a deterministic and finite time T follows a certain target distribution. First, we allow the insurance company to pay dividends and seek to maximise the expected discounted dividend payments or to minimise the ruin probability under the terminal distribution constraint that the surplus is Gaussian with given mean and variance. Here, we find explicit expressions for the optimal strategies in both cases, when the dividend strategy is updated at discrete points in time and continuously in time. Second, we let the insurance company buy a reinsurance contract for a pool of insured or a branch of business. In this setting we only allow for piecewise constant reinsurance strategies producing a normally distributed terminal surplus, whose mean and variance lead, e.g. to a given Value-at-Risk at some confidence level alpha. We investigate the question which admissible reinsurance strategy produces a smaller ruin probability, if the ruin-checks are due at discrete deterministic points in time. This presentation is based on an joint work with Julia Eisenberg (TU Vienna) and Benedetta Salterini (Univ. of Firenze) The seminar will take place on Thursday, 15 December at 12:00 PM in Room A202 - viale Romania 32, Roma.

Still, its learning mechanism is often too simplistic and many generalizations have been proposed to increase its flexibility, a popular one being the class of normalized completely random measures. Here we investigate a simple yet fundamental matter: will a different prior actually guarantee a different learning outcome? To this end, we develop a new framework for assessing the merging rate of opinions based on three leading pillars: i) the investigation of identifiability of completely random measures; ii) the measurement of their discrepancy through a novel optimal transport distance; iii) the establishment of general techniques to conduct posterior analyses, unravelling both finite-sample and asymptotic behaviour of the distance as the number of observations grows. Our findings provide neat and interpretable insights on the impact of popular Bayesian nonparametric priors, with very mild assumptions on the data-generating process. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/84498069342?pwd=ZkJOcnlNalEybmlEdE1QUGFEczZmdz09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

(PMS)^2 talk - Mario Maurelli - December 13 at 17.30
by Margherita Zanella 07 Dec '22

07 Dec '22

Dear colleagues, We are happy to announce the following online talk: Speaker: Mario Maurelli(Università di Pisa). Title: A McKean-Vlasov SDE and particle system with interaction from reflecting boundaries. Abstract: We consider a one-dimensional McKean-Vlasov SDE on a domain and the associated meanfield interacting particle system. The peculiarity of this system is the combination of the interaction, which keeps the average position prescribed, and the reflection at the boundaries; these two factors make the effect of reflection non local. We show path-wise well-posedness for the McKean-Vlasov SDE and convergence for the particle system in the limit of large particle number. Joint work with Michele Coghi, Wolfgang Dreyer, Peter K. Friz, Paul Gajewski, Clemens Guhlke. Date and time: Tuesday December 13, 17:30-18:30 (Rome time zone) Link: Entra nella riunione in Zoom https://polimi-it.zoom.us/j/92900386273?pwd=dG1xTUtsN0JpaFl2TWlzRTJ1a0lBZz09 ID riunione: 929 0038 6273 Passcode: 638099 This talk is part of the (PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico. Participation is free and welcome! Best regards The organizers (Carlo Orrieri, Maurizia Rossi, Margherita Zanella)

Buongiorno, con piacere segnalo il seguente seminario: -------------------------------- 14 dicembre ore 16.00 - aula 203, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Dott. Roberto Ascari Università di Milano-Bicocca Title: The flexible Latent Dirichlet Allocation Abstract: Over recent years, text modeling techniques have been employed in several applications, including the detection of latent topics in text documents. A widespread statistical tool for topic modeling is the Latent Dirichlet Allocation (LDA), which allows for a document representation in terms of topic composition. A well-known limitation of the LDA is related to the stiffness of the Dirichlet prior imposed on the topic distributions. To consider a richer dependence structure, we propose a generalization of the Dirichlet distribution as an alternative distribution, namely the flexible Dirichlet (FD). The FD is a distribution defined on the simplex space allowing for a finite mixture structure. This choice introduces additional parameters in the LDA, and ensures more flexibility, still maintaining the model interpretability, as well as conjugacy to the multinomial model. The latter property allows for a Collapsed Gibbs Sampling-based estimation procedure. The generalization of the LDA based on the FD distribution is illustrated via an application to a real dataset. ----------------------------------- Tutti gli interessati sono invitati a partecipare.

Seminar Wager @Bocconi - 12Dec at 12:00
by Giacomo Zanella 06 Dec '22

06 Dec '22

We are glad to announce the following hybrid seminar: Monday, 12 of December 2022 at 12:00 In person: Room 3-E4-SR03, floor 3, Bocconi University, Via Roentgen 1, Milan Zoom link: https://unibocconi-it.zoom.us/j/95882011831; Meeting ID: 958 8201 1831 Speaker: Stefan Wager (Stanford University) Title: Learning from a Biased Sample Abstract: The empirical risk minimization approach to data-driven decision making assumes that we can learn a decision rule from training data drawn under the same conditions as the ones we want to deploy it under. However, in a number of settings, we may be concerned that our training sample is biased, and that some groups (characterized by either observable or unobservable attributes) may be under- or over-represented relative to the general population; and in this setting empirical risk minimization over the training set may fail to yield rules that perform well at deployment. Building on concepts from distributionally robust optimization and sensitivity analysis, we propose a method for learning a decision rule that minimizes the worst-case risk incurred under a family of test distributions whose conditional distributions of outcomes Y given covariates X differ from the conditional training distribution by at most a constant factor, and whose covariate distributions are absolutely continuous with respect to the covariate distribution of the training data. We apply a result of Rockafellar and Uryasev to show that this problem is equivalent to an augmented convex risk minimization problem. We give statistical guarantees for learning a robust model using the method of sieves and propose a deep learning algorithm whose loss function captures our robustness target. We empirically validate our proposed method in simulations and a case study with the MIMIC-III dataset. Best regards, Giacomo Zanella

Corso Marta CATALANO (University of Warwick)
by Matteo Ruggiero 05 Dec '22

05 Dec '22

Cari colleghi, nell’ambito del programma di Visiting Professors della Laurea Magistrale in Stochastics and Data Science dell’Università di Torino (il programma completo è consultabile alla pagina https://www.master-sds.unito.it/go/visiting) con piacere annunciamo il seguente corso: -------------------------------------- MARTA CATALANO (University of Warwick) DEPENDENT NONPARAMETRIC PRIORS VIA COMPLETELY RANDOM MEASURES Bayesian nonparametrics provides a natural framework for performing flexible inference with principled quantification of uncertainty. The main ingredients are discrete random measures, whose laws act as prior distribution for infinite-dimensional parameters and, combined with the data, provide their posterior distribution. Recent works use dependent random measures to perform simultaneous inference across multiple samples. The borrowing of strength across different samples is regulated by the dependence structure of the random measures, with complete dependence corresponding to maximal sharing of information and fully exchangeable observations. In these lectures we start from the notion of completely random measure and describe several ways of introducing dependence between them. Different models may still induce the same amount of borrowing of information, measured by an index of dependence. In the two sample case, this is often achieved by second order summaries of the joint distribution through linear correlation. In the multivariate scenario, we characterise dependence in terms of distance from exchangeability by relying on optimal transport. This allows for informed prior elicitations and provides a fair ground for model comparison. -------------------------------------- Il corso si svolgerà solo in presenza secondo il seguente calendario Lez 1: mar 13/12: 14-16 - Aula 4 Lez 2: mer 14/12: 9.15-11.15 - Aula 4 Lez 3: mer 14/12: 14-16 - Aula 30 Lez 4: gio 15/12: 14-16 - Aula 11 Sede dei corsi: Corso Unione Sovietica 218/bis, 10134, Torino Il corso è rivolto agli studenti della Laurea Magistrale ma la partecipazione è aperta a tutti gli interessati.

Seminario Sapienza - Alberto Chiarini - Martedì 6 Dicembre
by Lorenzo Taggi 30 Nov '22

30 Nov '22

Titolo: On the cost of covering a fraction of a macroscopic body by a simple random walk. Abstract: In this talk we aim at establishing large deviation estimates for the probability that a simple random walk on the Euclidean lattice (d>2) covers a substantial fraction of a macroscopic body. It turns out that, when such rare event happens, the random walk is locally well approximated by random interlacements with a specific intensity, which can be used as a pivotal tool to obtain precise exponential rates. Random interlacements have been introduced by Sznitman in 2007 in order to describe the local picture left by the trace of a random walk on a large discrete torus when it runs up to times proportional to the volume of the torus, and has been since a popular object of study. In the first part of the talk we introduce random interlacements and give a brief account of some results surrounding this object. In the second part of the talk we study the event that random interlacements cover a substantial fraction of a macroscopic body. This allows to obtain an upper bound on the probability of the corresponding event for the random walk. Finally, by constructing a near-optimal strategy for the random walk to cover a macroscopic body, we discuss a matching large deviation lower bound. The talk is based on ongoing work with M. Nitzschner (NYU Courant). Martedì 6 Dicembre, ore 14:00 Dipartimento di Matematica, Sapienza Università di Roma, Sala di Consiglio Speaker: Alberto Chiarini, Università di Padova

[PRISMA] seminari di Antonio Lijoi e Federico Camerlenghi
by Domenico Marinucci 28 Nov '22

28 Nov '22

Care colleghe e colleghi il prossimo incontro del ciclo di seminari del gruppo UMI-Prisma si svolgerà come al solito il primo lunedì del mese, quindi il 5 dicembre dalle 16 alle 18 su piattaforma Teams (link alla fine del messaggio). Parleranno Antonio Lijoi e Federico Camerlenghi (cf. http://www.umi-prisma.polito.it/webinars.html) titoli ed abstract qui sotto: ------------------------------------------------------------------------------------------- Antonio Lijoi, Università Bocconi TITLE: Discrete random structures and Bayesian nonparametric modeling ABSTRACT: Discrete random structures, such as random partitions and discrete random measures, have emerged as effective tools for Bayesian modeling and have fueled exciting advances in density estimation, clustering, prediction, feature allocation and survival analysis. The Dirichlet process (DP) has undoubtedly emerged as a reference model, mostly due to its analytical tractability. Nonetheless, the DP shares also some well-known limitations that have spurred a very lively area of research aiming at the proposal and the investigation of more general and flexible discrete nonparametric priors. The talk will provide a broad overview of such classes of priors and will specifically focus on those obtained as normalization of completely random measures. Characterizations of the induced random partitions and predictive rules will be illustrated and their role in designing computational algorithms for the approximation of Bayesian inferences of interest will be highlighted, both in exchangeable and non-exchangeable settings. Federico Camerlenghi, Milano Bicocca TITLE: Normalized random measures with atoms' interaction ABSTRACT: The seminal work of Ferguson (1973), who introduced the Dirichlet process, has spurred the definition and investigation of more general classes of Bayesian nonparametric priors, with the aim at increasing flexibility while maintaining analytical tractability. Among the numerous generalizations, a fundamental class of random probability measures has been introduced by Regazzini et al. (2003): this is the class of normalized random measures with independent increments (NRMIs). NRMIs are random probability measures with almost surely discrete realizations, defined through the specifications of two ingredients: i) a sequence of unnormalized weights, which are the jumps of a Levy process on the positive real line; ii) a sequence of i.i.d. random atoms from a common base measure. The proposed construction is appealing from a mathematical standpoint, because analytical tractability is preserved, however NRMIs do not allow interaction among atoms, which are supposed to be independent and identically distributed. In some applied frameworks, the i.i.d. assumption could be too restrictive, for instance, in model-based clustering, when they are used as mixing measures in mixture models. To overcome this limitation, we propose a new class of normalized random measures with atoms' interaction. In our construction the atoms come from a finite point process, which is marked with i.i.d. positive weights. Thus, a new class of random probability measures is obtained by normalization. The desired interaction among atoms is then induced by a suitable choice of the law of the point process, which can create a repulsive or attractive behaviour. By means of Palm calculus, we are able to characterize marginal, predictive and posterior distributions for the proposed model. We specialize all our results for several choices of the finite point process, i.e., in the Determinantal, Gibbs and Shot-Noise Cox case. (Based on a joint work with Raffaele Argiento, Mario Beraha and Alessandra Guglielmi.) ------------------------------------------------------------------------- Grazie per l'attenzione, Domenico Marinucci Link per il collegamento: https://teams.microsoft.com/l/meetup-join/19%3a667d2414be564c5d8fba30acffeb… -- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Domenico Marinucci Dipartimento di Matematica Università di Roma Tor Vergata https://www.mat.uniroma2.it/~marinucc/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Title: Thermalization of 2D Quantum Memories* *Abstract: **The aim of a quantum memory is to protect an encoded quantum state against errors for long periods of time. Quantum double models are a class of 2D quantum memories proposed by Kitaev, in which the protection from noise is due to the topological properties of the ground state degeneracy.* *Heuristic arguments have long pointed to a weakness of these models against thermal noise processes. In this talk I will present a rigorous estimate on the lifetime of these memories under a noise process modeled by Davies generators which confirms these findings. This estimate is obtained by proving that the spectral gap of the generator is lower bounded by a positive constant uniformly in the system size.*

Padova Seminars in Probability and Finance - Giacomo Greco (Eindhoven University of Technology)
by Alberto Chiarini 27 Nov '22

27 Nov '22

Dear Colleagues, We would like to invite you to the following seminar that will take place on December 2nd at 11.00 in Padova. The seminar will be held in person and online via the Zoom platform. _____________________________________________________ Speaker: Giacomo Greco (Eindhoven University of Technology) Title: Entropic turnpike estimates for the kinetic Schrödinger problem Date and time: Friday, DECEMBER 2nd at 11.00 Place: room 2BC30 at the Department of Mathematics, University of Padova Zoom link: https://unipd.zoom.us/j/86210155315 available also on the webpage https://www.math.unipd.it/~bianchi/seminari/ Abstract: The kinetic Schrödinger problem consists in finding the most likely evolution of a system of i.i.d. particles driven by the underdamped Langevin dynamics, conditionally on their initial and final spatial configurations. In this model each particle is described both by its position and velocity, but there is no a priori knowledge of the velocities at the initial and final time. We will investigate the long-time behaviour of this kinetic system, proving that its most likely evolution is exactly the one that spends most of the time exponentially close to the equilibrium configuration (this property is commonly known in stochastic control theory as the turnpike property).

Dear all, I am delighted to announce the following Colloquium of The Department of Mathematics and Applications <https://www.matapp.unimib.it/it/eventi/colloquium-del-dipartimento-matemati…>, University of Milano-Bicocca combined with the "Seminario Matematico e Fisico di Milano <https://www.mate.polimi.it/smf/>”. Speaker: Gady Kozma (Weizmann Institute of Science, Rehovot). Title: Harmonic functions on groups. Abstract: The classic Liouville theorem states that any bounded harmonic function on Euclidean space is constant. The same holds for discretely harmonic functions on a lattice. But what happens when the Euclidean lattice is replaced by other graphs, in particular Cayley graphs of groups?

Seminar: Giovanni Pistone @University of Genova (DIMA)
by Fabio Rapallo 25 Nov '22

25 Nov '22

Dear all, we are glad to announce the following seminar: Speaker: professor Giovanni Pistone (de Castro Statistics, Collegio Carlo Alberto) Title: Affine Statistical Manifold: Finite State Space Date and time: Monday 28 november at 2 pm Place: room 508 at the Department of Mathematics, University of Genova YouTube channel: 508dima Abstract: H. Weyl defines an affine space as a triple (M, V, ->), where V is a real vector space and M is a set with a binary external operation such that the parallelogram law holds. This notion was introduced in Relativity to derive simple notions of velocity and acceleration for curves in non-flat spaces. I have extended this setup to vector bundles to discuss the relevant affine geometries of the probability simplex. This type of study was called Information Geometry by S-i Amari. Especially, Amari and Nagaoka introduced a crucial notion of duality between mixture families and exponential families. J. Aitchinson developed a similar geometrical treatment of what he calls Statistics of Compositional Data. This affine setup is compatible but different with the metric set due to CR Rao and based on the observation that the Fisher information matrix of a statistical model defines a Riemannian metric on the probability simplex. A previous lecture on similar topics is transcribed at http://www.j-npcs.org/online/vol2020/v23no2p221.pdf. The present lecture is based on the material taken from https://arxiv.org/abs/2204.00917, https://www.mdpi.com/1099-4300/20/2/139, and https://arxiv.org/abs/1502.06718.<https://arxiv.org/abs/1502.06718> The continuous case, not treated here, requires particular technical notions of differential geometry and functional analysis. See a summary at https://arxiv.org/abs/2210.07641 The seminar will be held in person and online via the YouTube channel: 508dima.
