考虑Markov分支过程的前对偶过程.对偶分支过程,它是一类特殊的具有突变率的人口过程,证明了如果对偶分支过程在满足常返的条件下,它具有遍历及指数遍历性,并给出了该过程的遍历性及指数遍历性的充分必要条件.
We consider the pre-dual process of the ordinary Markov Branching Process, it is a special Population process with catastrophe. Under the condition of the recurrence, it has the properties of ergodicity and exponential ergodicity, and we obtain the necessary and sufficient conditions for its ergodicity and exponential ergodicity.
