Probability Webminar: Saeda Marello (University of Bonn) [Padova 22/05, 11.00]
by alessandra bianchi 13 May '20

13 May '20

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on May 22 at 11 by the zoom platform. ________________________________________________________ Speaker: Saeda Marello (University of Bonn) Title: Metastability for the randomly dilute Curie-Weiss model with Glauber dynamics". 22 MAY (Friday) - 11:00 - zoom link: TBA The link and password to access the seminar will be available the day of the seminar at the following webpage https://www.math.unipd.it/news/metastability-for-the-randomly-dilute-curie-… Abstract: The Curie-Weiss model (CW) is a classical model of a ferromagnetic spin system in which all spins interact with each other, namely the interaction graph is complete. The randomly dilute Curie-Weiss model (RDCW) is a generalisation of the CW in which the deterministic interaction between pairs of spins is replaced by iid random coefficients. It can be also viewed as an Ising model on a random graph. We will show results in the case where the interaction coefficients are iid Bernoulli random variables with fixed parameter p, i.e. the interaction graph is an Erdős–Rényi random graph. After giving an introduction on metastability and on the well known results for the CW, we will focus on how the mean metastable hitting time in the RDCW can be approximated by that of the CW, asymptotically as the system size grows. The main methods we used are potential theoretic approach to metastability and concentration of measure inequalities. Based on joint work with Anton Bovier and Elena Pulvirenti. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Webinar CASTILLO

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/research/webinars/> Venerdì 15 Maggio 2020, alle ore 12:00, si terrà il seguente webinar: ------------------------------------------------ Ismael CASTILLO (Sorbonne Université Paris) *Multiscale analysis of Bayesian CART* Abstract: This work affords new insights about Bayesian CART in the context of structured wavelet shrinkage. We show that practically used Bayesian CART priors lead to adaptive rate-minimax posterior concentration in the supremum norm in Gaussian white noise, performing optimally up to a logarithmic factor. To further explore the benefits of structured shrinkage, we propose the g-prior for trees, which departs from the typical wavelet product priors by harnessing correlation induced by the tree topology. Building on supremum norm adaptation, an adaptive nonparametric Bernstein–von Mises theorem for Bayesian CART is derived using multiscale techniques. For the fundamental goal of uncertainty quantification, we construct adaptive confidence bands with uniform coverage for the regression function under self-similarity. (joint work with Veronika Rockova, University of Chicago). ------------------------------------------------ Chiunque volesse collegarsi al webinar è pregato di inviare una email entro mercoledi 13 Maggio a pierpaolo.deblasi(a)unito.it Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats in collaborazione con il Collegio Carlo Alberto.

------------------------------------------------ UNIVAQ RANDOM TALKS ________________________________ Online talks on Probability and Applications at DISIM - UNIVERSITÁ DI L'AQUILA Using Zoom Videoconference system Monday 18th 2:30 p.m. Prof. Giorgio Ferrari - Bielefeld University TITLE: Singular Control of the Drift of a Brownian System Everybody is welcome, please subscribe by the following form The day of the seminar, participants will receive an invitation by e-mail [https://lh5.googleusercontent.com/CWhLsT4lqNWzIjVe3mEN_7Iq4wxE9g204khy6mYxf…]<https://docs.google.com/forms/d/e/1FAIpQLSclukp_QZeujS15nbL3IvtRKGJWvHkx-E5…> UNIVAQ RANDOM TALKS 3 - UNIVERSITÁ DI L'AQUILA<https://docs.google.com/forms/d/e/1FAIpQLSclukp_QZeujS15nbL3IvtRKGJWvHkx-E5…> ONLINE May 18th 2020 - 2:30 p.m. Prof. Giorgio Ferrari - Bielefeld University: Singular Control of the Drift of a Brownian System docs.google.com No need to subscribe, if, in a previous form, you asked to be always included ABSTRACT: Consider a standard Brownian motion whose drift can be increased or decreased in a possibly singular manner. The objective is to minimize an expected functional involving the time-integral of a running cost and the proportional costs of adjusting the drift. The resulting two-dimensional degenerate singular stochastic control problem with interconnected dynamics is solved by combining techniques of viscosity theory and free boundary problems. We provide a detailed description of the problem's value function and of the geometry of the state space, which is split into three regions by two monotone curves. Our main result shows that those curves are continuously differentiable with locally Lipschitz derivative and solve a system of nonlinear ordinary differential equations. The optimal control is also constructed (weakly) under further specifications of the model. This talk is based on a joint work with Salvatore Federico (University of Siena) and Patrick Schuhmann (Bielefeld University). --------------------------------- Fabio Antonelli DISIM - Università di L'Aquila
