一类纯跳种群系统的遍历性
Ergodicity for a class of pure-jump population systems
摘要
Abstract
To characterize the effects of stochastic environment and major mutation factors on populations,we consider a class facultative population system based on Markov chains and pure-jump stable processes.First of all,the existence and uniqueness of a global positive solution of the proposed model is discussed.Then,sufficient conditions for ergodicity are specified.Finally,conditions for positive recurrence of the model are presented.关键词
