Coupling, ergodicity and transportation inequalities for SDEs with jumps Majka, Mateusz

Description

We present a construction of a coupling of solutions to a certain class of SDEs with jumps, which includes SDEs driven by symmetric $\alpha$-stable processes with $\alpha \in (1,2)$. As an application, we quantify the speed of convergence of solutions to such equations to their invariant measures, both in the standard $L^1$-Wasserstein and the total variation distances. As a second application, we obtain some transportation inequalities, which characterize concentration of the distributions of these solutions, and which were previously known only under the global dissipativity assumption on the drift.
