内容摘要:

We develop the coupling method to establish a stochastic comparison theorem for the state-dependent regime-switching diffusion processes. This enables us tocontrol pathwisely the evolution of the state-dependent jumping process simplyby Markov chains. As applications, some existing results on the stability and ergodicity for state-independent regime-switching processes are extended to thestate-dependent case.  Moreover, agradient estimate for the continuous component of the regime-switching processis established
