Birth-death process differential equation

Websimple birth and death process is studied. The first two moments are obtained for the general process and deterministic solutions are developed for several special models … WebWhen a birth occurs, the process goes from state n to n + 1. When a death occurs, the process goes from state n to state n − 1. The process is specified by positive birth rates and positive death rates . Specifically, denote the process by , and . Then for small , the function is assumed to satisfy the following properties:
