The Berlin-Oxford International Research Training Group (IRTG) 2544 “Stochastic Analysis in Interaction” offers 8 PhD positions (75% TVL E 13, about 1900 EUR p.m. after taxes, social security...) for 3 years starting April 1st, 2023, or soon thereafter. Funded by the Deutsche Forschungsgemeinschaft (DFG), the IRTG is a joint research initiative of the stochastic analysis group of FU, HU, TU and WIAS Berlin with its counterpart at the University of Oxford. The advertised positions will be based in Berlin and will offer ample opportunities to interact also with members of the Oxford team, most notably in a 6-months exchange. Embedded in a truly international environment, the IRTG students will get excellent research training in a structured programme focussing on challenges at the mathematical foundations of Stochastic Analysis as well as on challenges arising from its various applications, e.g., in physics, biology, finance or data science. The combined expertise from the Berlin and Oxford groups will provide a significant breadth in depth and fertile ground for our students' ambitious research ideas. Successful candidates will have an MSc degree (or equivalent) in Mathematics (or a closely related field), strong knowledge of stochastic analysis, and feel eager to engage in the exchange of ideas with the teams in both Berlin and Oxford. Deadline for applications is December 9, 2022. Please see https://stellenticket.de/157323/TUB/?lang=en for the official job ad and for instructions on how to apply. Our IRTG webpage www.math.tu-berlin.de/irtg offers more information on the Berlin-Oxford IRTG 2544.

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

Seminario del Prof. Consiglio - 6 dicembre 16.00
by Enea Bongiorno 29 Nov '22

29 Nov '22

Buongiorno, con piacere segnalo il seguente seminario: -------------------------------- 6 dicembre ore 16.00 - aula 101, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Prof. Andrea Consiglio Università di Palermo Title: Simulation and Optimization Models to Assess Sovereign Debt Sustainability Abstract: We model sovereign debt sustainability with optimal financing decisions under macroeconomic, financial, and fiscal uncertainty, with endogenous risk and term premia. Using a coherent risk measure we trade off debt stock and flow risks subject to sustainability constraints. We optimize static and dynamic financing strategies and demonstrate economically significant savings from optimal financing compared with simple rules and consols, and find that optimizing the trade-offs can be critical for sustainability. ----------------------------------- Tutti gli interessati sono invitati a partecipare.

[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/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
