Talks from

Title: A gradient flow approach to the Boltzmann equation

Abstract: In this talk I will present a new point of view on the spatially homogeneous Boltzmann equation viewing it as the gradient flow of the entropy. This gradient flow structure relies on a new notion of distance between probability measures that takes the collision process between particles into account and takes over the role of the Wasserstein distance. As two applications of this point of view I will present a time-discrete variational approximation scheme for the homogeneous Boltzmann equation and a new and simple proof for the convergence of Kac's random walk to the Boltzmann equation.

Title: New results about the link between entropic and displacement interpolations Slides

Abstract: After reviewing the notion of entropic interpolation, I shall discuss in which sense it can be used to provide a second order approximation of the classical displacement interpolation both in the smooth and in the non-smooth setting. The main application of this result is the second order differentiation formula on RCD spaces. From a work with Luca Tamanini.

Title: Ricci curvature bounds for discrete and quantum systems

Title: Some smooth applications of non-smooth Ricci curvature lower bounds. Slides
