Conditional propagation of chaos for systems of interacting particles with simultaneous nearly-stable jumps
Elisa MARINI (Université Paris Dauphine)
We consider a system of $N$ interacting particles, described by SDEs driven by Poisson random measures, where the coefficients depend on the empirical measure of [...]

On characteristic length for Activated random walk on the line.
Félix ROUVEYRE (Aix-Marseille Université)
The concept of self-organized criticality was introduced by Bak, Tang and Wiesenfeld to provide a framework for understanding the emergence, in various contexts, of systems [...]

Phase transitions in charged polymer models
Julien POISAT (Université Paris Dauphine)
I will review some old and recent results on the topic of charged polymer models. Those are random walk models with disordered interaction at self-intersections, [...]

How to construct a planar Brownian motion from simple path and loops
Isao Sauzedde (ENS Lyon)
During this talk, I will present a joint paper with N. Berestycki in which we introduce and study a map which takes as inputs a [...]

Mean-field analysis of the training dynamics of two-layer neural networks
Arnaud Descours (ISFA, Lyon)
Training neural networks via stochastic gradient descent (SGD) amounts to solving a complex, non-convex optimization problem. Inspired by statistical mechanics, the mean-field approach provides a [...]

The partition function of β-ensembles with complex potentials
Alex Little (ENS Lyon)
The asymptotic behaviour of the partition function is one of the central questions of statistical mechanics. In our work we consider this problem when the [...]
