Stability Of A Class Of Stochastic Partial Differential Equations With Semi Markov Switching And Jumps

In this paper, we shall use Yosida approximation to discuss the sta-bility of a class of stochastic partial differential equations with semi Markov switching and juamps. Our main results include:(i) existence and uniqueness of mild solutions;(ii) corresponding Markov processes and genenrators;(iii) sufficient conditions for exponential stability.Our results is an extension of existing results. The existing result is the deduction of our result.
