Fubao Xi, Chao Zhu

摘要:

本文考虑一类弱耦合Lévy型算子的鞅问题.证明了在适当的条件下,该鞅问题是适定的,且唯一地决定强马尔可夫过程$(X,Λ)$ .通过耦合方法进一步证明了具有Lévy型跳变的状态切换跳扩散过程$(X,Λ)$在非利普希茨条件下具有Feller和强Feller性质.

英文摘要:

This paper considers the martingale problem for a class of weakly coupled Lévy type operators. It is shown that under some mild conditions, the martingale problem is well-posed and uniquely determines a strong Markov process $(X,Λ)$. The process $(X,Λ)$, called a regime-switching jump diffusion with Lévy type jumps, is further shown to posses Feller and strong Feller properties under non-Lipschitz conditions via the coupling method.
