Seminario Dip. Scienze Statistiche, Sapienza - M. Mazza - 18-4-2024
by Luisa Beghin 14 Apr '24

14 Apr '24

Buongiorno, *giovedì 18 Aprile alle ore 15:00,* nell'*aula 24 del Dipartimento di Scienze Statistiche, Sapienza* (ed. CU002, quarto piano) e online al link https://uniroma1.zoom.us/j/83831966596?pwd=U1pEclcrZzlFMXppcmVaL1FOaFUydz09 si terrà il seguente seminario: *Speaker: Mariarosa Mazza (Università di Roma, Tor Vergata)* *Titolo: Fractional derivatives and models: some numerical aspects* *Abstract:* Fractional derivatives are a well-established mathematical tool that has received much attention in recent decades due to their non-local behavior, proven to be useful in modeling anomalous diffusion present in various real-world phenomena. Examples include the generation and spread of electrical signals across biological excitable tissues, interactions between particles and fields within a plasma, and network dynamics in human environments. The improvement in describing these phenomena, however, results in a more challenging numerical treatment, requiring specialized strategies, e.g., in terms of discretization methods or numerical solvers. The aim of this talk is to give a little taste of the topic with a focus on the numerical linear algebra difficulties that it poses. Grazie per l'attenzione, cordiali saluti.

Seminar: Francesca Romana Crucinio April 16, 2024, DAIS - Ca' Foscari University of Venice
by Carlo Gaetan 11 Apr '24

11 Apr '24

Dear all, we are glad to announce the following *online* seminar *April 16, 2024, 12:15 PM* Zoom: https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Francesca Romana Crucinio, King's College London *Title*: A connection between Tempering and Entropic Mirror Descent *Abstract:* This talk explores the connections between tempering (for Sequential Monte Carlo; SMC) and entropic mirror descent to sample from a target probability distribution whose unnormalized density is known. We establish that tempering SMC corresponds to entropic mirror descent applied to the reverse Kullback-Leibler (KL) divergence and obtain convergence rates for the tempering iterates. Our result motivates the tempering iterates from an optimization point of view, showing that tempering can be seen as a descent scheme of the KL divergence with respect to the Fisher-Rao geometry, in contrast to Langevin dynamics that perform descent of the KL with respect to the Wasserstein-2 geometry. We exploit the connection between tempering and mirror descent iterates to justify common practices in SMC and derive adaptive tempering rules that improve over other alternative benchmarks in the literature.

Seminar Tommaso Rosati at Tor Vergata 17.04
by Michele Salvi 11 Apr '24

11 Apr '24

Dear all, On Wednesday, April 17th, at 14h30 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Tommaso Rosati (University of Warwick) with the seminar "Lower bounds to Lyapunov exponents of stochastic PDEs” Abstract: Inspired by problems from fluid dynamics, we introduce an approach to obtain lower bounds to Lyapunov exponents of stochastic PDEs. Our proof relies on the introduction of a Lyapunov functional for the projective process associated to the equation, based on the study of dynamics of energy level sets and on a notion of non-degeneracy of the noise that leads to high-frequency stochastic instability. We address some nonlinear problems. Joint works with A. Blessing , M. Hairer, and (in progress) with M. Hairer, S. Punshon-Smith and J. Yi. We encourage in-person partecipation.

Assistant Professor (Tenure Track) in Mathematical Methods of Economics, Finance, and Actuarial Sciences at Ca Foscari, University of Venice
by giulia.iori＠unive.it 11 Apr '24

11 Apr '24

Dear Colleagues, I would like to draw your attention to the approaching deadline for the following academic position (April 14th 2024, AT 1:00 P.M. CET) The Department of Economics at Ca’ Foscari University of Venice is currently seeking applications for an Assistant Professor (Tenure Track) (RTT) in Mathematical Methods of Economics, Finance, and Actuarial Sciences (13/D4 – SECS-S/06). This tenure track opportunity offers a pathway to tenure as an Associate Professor within a timeframe of three to six years, contingent upon a positive evaluation from the department and attainment of the Italian national habilitation to an associate professorship. The Economics Department at Ca Foscari has been recognized as a "Department of Excellence" by the Italian Ministry of Education, University, and Research, securing special financial support for the 2023/2027 period. The department consistently ranks favourably for research output across national and international research rankings. We encourage applications from candidates with a strong research track record whose research aligns with the core themes of the SECS-S/06 disciplinary sector. Ideal candidates will possess expertise in mathematical models and methodologies pertinent to economics, finance, and actuarial sciences. This includes but is not limited to quantitative finance, decision theory, risk and uncertainty management, and the application of agent-based and computational methods (including data analysis). Successful candidates will exhibit a strong commitment to delivering high-quality teaching. The department offers courses taught in both Italian and English at various academic levels, though knowledge of Italian is initially not required. We welcome applications from international scholars. For those based abroad, special conditions apply, and they may benefit from a favourable tax waiver scheme. For additional information concerning the Department of Economics visit http://www.unive.it/pag/28365/. For queries about the application process please contact recruiting.dec(a)unive.it Application Procedure: Apply online at https://bandi.mur.gov.it/jobs.php/public/job/id_job/118942 http://www.unive.it/bandi-ric240 Application deadline: April 14th 2024, AT 1:00 P.M.

SMF: François Delarue at Milano-Bicocca (Apr 18, 2024)
by Maurizia Rossi 10 Apr '24

10 Apr '24

Dear colleagues, I am glad to announce the following talk which is part of the *"Seminario Matematico e Fisico di Milano" *activities. Speaker: *François Delarue* (Univ. Côte d'Azur) Title:* Mean field control and games. Some prospects. * *Time and place:* April 18, 2024 - 2:00pm-3:00pm - building U5/room 3014 Dept. of Mathematics and Applications, Univ. Milano-Bicocca. *Abstract:* I will first give a brief overview of the notion of mean-field control and games. In particular, I will focus on the Eulerian formulation, through the notion of master equation, which is a nonlinear PDE on the space of probability measures. This PDE is notoriously difficult to solve, at least in a classical sense, except in cases presenting a form of convexity or monotonicity in the argument of the measure. I will then present two problems outside the convex/monotonic framework: (i) non-convex mean-field control problems and their particle approximation, (ii) mean-field games subject to certain non-standard forms of common noise. Best wishes, Maurizia Rossi -- Maurizia Rossi Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://mauriziarossi.wordpress.com
