Title:" Transfer Operators and Banach Space Techniques in Ergodic Theory "
Speaker: Pedro Augusto da Silva Morelli - I.C.M.C., Universidade de São Paulo, São Carlos
Abstract: The study of statistical properties of dynamical systems has witnessed in recent years the development powerful new tool: the functional approach. This method focuses on how measures evolve under the dynamics, rather than on individual trajectories by analyzing the spectral properties of the transfer operator on suitable Banach spaces. In this talk, I will introduce this viewpoint in ergodic theory and illustrate its application through examples. Time permitting, I will also discuss some recent refinements of the classical theory.

Schedule: - 16:00 - Rome Time -
Where: Conference Room 1201" R. Dal Passo "
Title:" Bose-Einstein Condensation and low temperature phases of Dilute Bose Gases "
Speaker: Serena Cenatiempo - GSSI - Gran Sasso Science Institute
Abstract:
Dilute Bose gases are unique quantum systems that exhibit a fascinating low-temperature phase known as the Bose-Einstein condensate.
Over the past two decades, the mathematical understanding of these systems has improved considerably. In this talk, we will review some of these
advances, with a perspective on the largely open challenge of understanding their general behaviour in the thermodynamic limit, the appropriate
large-scale framework for investigating the occurrence of phase transitions.
Based on a series of joint works with G. Basti, C. Boccato, C. Brennecke, A. Giuliani, A. Olgiati, G. Pasqualetti and B. Schlein.

DIFFERENTIAL EQUATIONS SEMINAR
Date: 11th November 2025
Schedule: 14:30 - Rome Time -
Where: Conference Room "R. Dal Passo "
Title: " Quantitative stability of optimal transport maps "
Speaker: Cyril Letrouit - C.N.R.S., Laboratoire d' Orsay, Paris Saclay
Optimal transport consists in sending a given source probability measure ρ to a given target probability measure μ in an optimal way with respect to a certain cost. Optimal transport has been widely used in many fields, including analysis, probability, statistics, geometry, and optimization. Under classical assumptions, there exists a unique optimal transport map from ρ to μ (Brenier's, McCann's theorems, etc.). In this talk based on a collaboration with Quentin Mérigot, we provide a quantitative answer to the following stability question, notably motivated by numerical analysis and statistics: if μ is perturbed, can the optimal transport map from ρ to μ change significantly? The answer depends on the properties of the source measure ρ. We will also explain some mechanisms leading to instability and present a few conjectures.
