Abstract
By using Bismut's approach to the Malliavin calculus with jumps, we establish a derivative formula of Bismut-Elworthy-Li's type for SDEs driven by multiplicative Lévy noises, whose Lévy measure satisfies some order conditions. In particular, α-stable-like noises are allowed. Moreover, we also obtain the sharp gradient estimate in short time for the corresponding transition semigroup provided α∈(1,2).
