On uniform in time propagation of chaos in metastable cases: the Curie-Weiss model
Lucas Journel, Pierre Le Bris
Many low temperature particle systems in mean-field interaction are ergodic with respect to a unique invariant measure, while their (non-linear) mean-field limit may possess severa…

Convergence of a particle approximation for the quasi-stationary distribution of a diffusion process: uniform estimates in a compact soft case
Lucas Journel, Pierre Monmarché
We establish the convergences (with respect to the simulation time ; the number of particles ; the timestep ) of a Moran/Fleming-Viot type particle scheme toward the quasi…
