Optimal linear drift for the speed of convergence of an hypoelliptic diffusion

Probability 2021-10-07 v4

Abstract

Among all generalized Ornstein-Uhlenbeck processes which sample the same invariant measure and for which the same amount of randomness (a NN-dimensional Brownian motion) is injected in the system, we prove that the asymptotic rate of convergence is maximized by a non-reversible hypoelliptic one.
