针对一类带泊松跳的随机微分方程,在一些合理的条件假设下研究了该类方程解的半群的 Harnack 不等式和 Log-Harnack 不等式问题。首先建立了两类半群之间的关系,同时使用耦合方法,结合 Girsanov 定理、H?lder 不等式、Young 不等式以及 Ito 公式,先后获得了 Harnack 和 Log-Harnack 的2种不等式。 t

In this paper, we study a class of stochastic differential equations with Poission jumps. Under some reasonable conditions, we deal with the issue of the Harnack inequalities and the Log-Harnack inequalities for the semigroup of the solutions of such equations. We establish the relationship between the two kinds of semigroup. We also obtain two inequalities such as Harnack and Log-Harnack using the coupling argument, along with Girsanov theorem, H?lder inequality, Young inequality and Ito formula.
