给定了随机环境中分枝过程(BPRE)的精确定义,讨论了有关的可测性问题和BPRE的基本性质.在此基础上,证明了BPRE的一个等价定理.
An exact formulation of the definition of branching processes in random environments (BPRE) is given. The related measurability and some other basic properties of BPRE are discussed. Based on those results, a theorem of equivalence about BPRE is established.
