摘要:

本文考虑一类带移民和拯救的二次加权分枝过程(QWMBPIR)的正则性、存在唯一性以及常返性和遍历性.我们首先对QWMBIR的q-矩阵发生函数的性质进行讨论,建立QWMBPIR正则性及唯一性的判别准则.进一步,对QWMBPIR的常返性及遍历性进行分析,得到过程遍历性的充分条件.

Abstract:

In this paper we study the regularity,uniqueness,recurrence and ergodicity of the quadratic weighted Markov branching processes with immigration and resurrection(QWMBPIR).Firstly,we investigate the properties of the generating function for QWMBIR q-matrix.It is proved that the QWMBPIR is regular and unique.Then we discuss the recurrence and ergodicity of QWMBPIR and give a sufficient condition for the ergodicity.
