摘要: In this talk, we survey the unified treatment for various criteria on classical problems (including uniqueness, recurrence, ergodicity, exponential ergodicity, strong ergodicity, as well as extinction probability etc.) for single birth processes, which follows from a new explicit representation of the solution to the Poisson equation. Meanwhile, a new representation of stationary distribution for ergodic single death processes and the mean occupation time for transient single birth processes are presented. This talk is mostly based on a joint work with Professor Mu-Fa Chen.
