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, [...]

Extreme paths in oriented 2D Percolation - Enrique Andjel
Enrique Andjel (I2M, Aix-Marseille Université)
A useful result about leftmost and rightmost paths in two dimensional bond percolation is proved. Among the consequences are a natural monotonicity in the probability [...]
Quenched invariance principle for random walks with time-dependent ergodic degenerate weights - Alberto Chiarini
Alberto Chiarini (I2M, Aix-Marseille Université)
We study a symmetric diffusion in divergence form in a stationary and ergodic environment, with measurable unbounded and degenerate coefficients. We prove a quenched invariance [...]
Complémentabilité et maximalité, en théorie ergodique et en théorie des filtrations - Christophe Leuridan
Christophe Leuridan (Institut Fourier, Université de Grenoble-Alpes)
Soit $(E,{\cal E},\pi,T)$ un système dynamique. Un facteur de $T$ est une sous-tribu de ${\cal E}$ invariante par $T$. Un facteur ${\cal A}$ est dit [...]
