Seminario di Giorgio Cipolloni a Roma Tre il 20 giugno alle 14
by Pietro Caputo 07 Jun '23

07 Jun '23

Martedì 20 giugno 2023 alle ore 14:00, Aula 211 Dipartimento di Matematica e Fisica di Roma Tre, Largo San Leonardo Murialdo,1- 00146 Roma. Speaker: Giorgio Cipolloni (Princeton Center for Theoretical Science) Title: Quantum Unique Ergodicity and its fluctuations for Wigner matrices. Abstract: We prove that the eigenvectors of Wigner matrices satisfy the Eigenstate Thermalization Hypothesis (ETH), which is a strong form of Quantum Unique Ergodicity (QUE) with optimal speed of convergence. Then, using this a priori bound as an input, we analyze the Stochastic Eigenstate Equation (SEE) and prove a Wigner matrix analog of the Berry random wave conjecture.

SPASS Seminar: Erwin Luesink
by Andrea Agazzi 07 Jun '23

07 Jun '23

Dear Colleagues, We would like to invite you to the following SPASS <https://sites.google.com/unipi.it/spass> seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *A geometric approach to deriving and numerically integrating models with transport-type noise in geophysical fluid dynamics.* by *Erwin Luesink *(Imperial College London) The seminar will take place on *TUE, 13.06.2023* at *14:00 CET* in Aula Volterra, Scuola Normale Superiore (please note the unusual venue) and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass --------------------------------------- Abstract: *In this talk I will discuss how the framework of geometric continuum mechanics can be made stochastic by introducing the stochastic Euler-Poincare theorem. This naturally leads to noise of transport type in fluid dynamics while maintaining geometric invariants, such as the enstrophy in two-dimensional ideal fluids. In special cases, it is possible to discretise the equations of motion while preserving most of the structure, which provides strong numerical evidence for Kraichnan’s double cascade conjecture in two-dimensional incompressible fluids. I will also discuss some recent progress for the quasi-geostrophic equations.*

announcement Vienna WPI Workshop- looking for contributed speakers
by Viktoria Schildhammer 05 Jun '23

05 Jun '23

Dear colleagues, We would like to announce the following workshop “Stochastics, Statistics, Machine Learning and their Applications to Sustainable Finance and Energy Markets” taking place at the Wolfgang Pauli Institute (WPI) in Vienna, Austria from the 11.09.2023-14.09.2023 (https://wpi.univie.ac.at/) The workshop aims at bringing together an interdisciplinary group of leading researches with interest in stochastic methods for sustainable finance and energy markets. Particular emphasis will be given to Environmental Social Governance (ESG) finance, climate/weather modeling, optimal control problems and optimal contract theory e.g. in view of fostering renewable energy sources The workshop starts on September 11, 2023, with two graduate courses held by Roxana Dumitrescu and Matheus Grasselli in the areas of green finance, climate modeling, renewables in energy markets and optimal control. The graduate courses are meant for Phd and advanced Master students and roughly correspond to 1 ECTS. A background in probability theory, applied stochastic processes, and statistics is recommended. These courses are then followed by 3 full conference days. The goal is to provide a platform for exchanging new ideas among different research communities and initiate interdisciplinary collaborations. In particular a dedicated time for discussions will be scheduled on each day of the workshop. Beside the keynote speakers, there will be a limited amount of slots for contributed talks. We thus invite interested researchers including Phd students to present their recent work at the workshop. If you would like to give a contributed talk, please send the title and abstract in a plain text email to: wpi-stostaml.2023(a)univie.ac.at The submission deadline is 10.06.2023. Please also mention which days of the workshop you would be able to participate. The organizing committee will review the abstracts and will get back to you by approximately end of June to let you know if your talk has been accepted. Attending the workshop is for free, but please register via email to wpi-stostaml.2023(a)univie.ac.at The registration deadline is 01.08.2023. Please also mention which days of the workshop you would be able to participate. In case of problems / questions, please do not hesitate to send us an e-mail (wpi-stostaml.2023(a)univie.ac.at) We are looking very much forward to welcoming you in Vienna in September!

Seminar in Statistics - CLAUDIA STRAUCH

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 9 Giugno 2023, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Claudia Strauch* (Aarhus University, Denmark) Title: *On nonparametric approaches to stochastic control* Abstract: Theoretical solutions to stochastic optimal control problems are well understood in many scenarios; however, their practicability suffers from the assumption of known dynamics of the underlying stochastic process. This raises the challenge of developing purely data-driven strategies, which we explore for ergodic singular control problems associated to continuous diffusions and Lévy processes. In particular, we describe the specific statistical challenges arising in the stochastic control context, and we provide a brief overview of the current state-of-the-art for nonparametric inference of scalar and multidimensional diffusion processes. Finally, we show how these findings translate into exact rates of convergence of polynomial order for the regret for the considered control problems. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/86072582856?pwd=c3RveWVHTjdzTERiVnFra3RpVWJTQT09> 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/>
