Birth death process is a special kind of markov chain, and some scholars, such as Zikun Wang et al., have had deep and important research in these areas. On this foundation, in this paper, difference equations is composed in the method of recursion because of the strong markov property of bilateral Birth-Death Processes. And the divergent time is expressed via natural measure and primary measure. At last, the divergence speed of bilateral Birth-Death Processes is discussed. |
