On the Long-term Behavior for Sub-stationary Markov Processes
摘要
We study the long-term behavior of sub-stationary Markov processes, mainly including establishing the functional law of large numbers, the functional central limit theorem, and the quasi-stationary theorem for them. For symmetric Markov processes, we give a precise characterization of the parameters related to their long-term behavior. Finally, we provide easy-to-check conditions that ensure the satisfactory long-term behavior of the Feynman-Kac subprocesses derived from symmetric Markov processes killed by multiplicative functionals.
