Gradient estimates for SDEs Driven by Multiplicative L\'evy Noise

Probability 2015-05-28 v2 Analysis of PDEs

Abstract

Gradient estimates are derived, for the first time, for the semigroup associated to a class of stochastic differential equations driven by multiplicative L\'evy noise. In particular, the estimates are sharp for α\alpha-stable type noises. To derive these estimates, a new derivative formula of Bismut-Elworthy-Li's type is established for the semigroup by using the Malliavin calculus and a finite-jump approximation argument.
