报告题目：Asymptotic Properties of Stochastic Hamiltonian Type Jump Diffusion Systems with Countable Regimes
报告摘要：In this talk we give an introduction to the stochastic systems with regime-switching, then focus on a class of stochastic Hamiltonian type jump diffusion system with state-dependent switching, in which the switching component has countably infinite many states. First, we prove the existence and uniqueness of the underlying processes by virtue of successive construction methods. Next, we establish the Feller property by coupling methods. Furthermore, we prove the strong Feller property by introducing some auxiliaryprocesses and making use of appropriate Radon-Nikodym derivatives.Finally, on the basis of the above results, we obtain the exponential ergodicity under the Foster-Lyapunov drift condition.
