摘 要:Gradient estimates are derived, for the first time, for the semigroup associated to a class of stochastic differential equations driven by multiplicative Levy noise. In particular, the estimates are sharp for \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. This is a joint work with Feng-Yu Wang and Xicheng Zhang.
