By assuming that the SDE has a unique solution, we obtain gradient estimates of the associated semigroup when the drift term is locally H\\\"{o}lder continuous, and we establish the ergodicity of the process both in the $L^1$-Wasserstein distance and the total variation, when the coefficients are dissipative for large distances. The proof is based on a new explicit Markov coupling for SDEs driven by multiplicative pure jump L\\'{e}vy noises, which is derived for the first time in this paper.", "revisions": [ { "version": "v1", "updated": "2018-01-18T04:56:25.000Z" } ], "analyses": { "keywords": [ "sdes driven", "multiplicative lévy noises", "gradient estimates", "ergodicity", "multiplicative pure jump" ], "note": { "typesetting": "TeX", "pages": 34, "language": "en", "license": "arXiv", "status": "editable" } } }
