Propagation of chaos in Fisher information
Jules Grass, Arnaud Guillin, Christophe Poquet
We present a new method for proving sharp local propagation of chaos in Fisher Information for particles with smooth interaction and drift. We rely on a new Lemma computing the Fis…

Sharp propagation of chaos for McKean-Vlasov equation with non constant diffusion coefficient
Jules Grass, Arnaud Guillin, Christophe Poquet
We present a method to obtain sharp local propagation of chaos results for a system of N particles with a diffusion coefficient that it not constant and may depend of the empirical…
