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, [...]

Spectre des matrices de Toeplitz bruitées
Charles BORDENAVE (I2M, AMU)
Résumé : Travail en cours et en collaboration avec Mireille Capitaine et François Chapon. Les matrices de Toeplitz forment une classe très riche de matrices possiblement non-normales mais [...]

Mixing time and cutoff for simple random walks on the Chung-Lu directed graph
Giacomo PASSUELLO (Univ. de Padoue)
In this talk, we consider a simple random walk defined on a Chung-Lu directed graph. This is an inhomogeneous random network that extends the Erdős-Renyi [...]

Genealogies of records of stochastic processes with stationary increments as unimodular trees.
(...)
Abstract: Consider a stationary sequence $X=(X_n)$ of integer-valued random variables with mean $m in [-infty, infty]$. Let $S=(S_n)$ be the stochastic process with increments $X$ [...]
