WebMay 10, 2024 · Let λ 0 = 0, as we only care about the first return to 0. This makes 0 an absorbing state. Let a ( n) denote the probability that a population will ever reach 0, given that it started with X 0 = n. Then we have the following: a ( n) = λ n λ n + μ n a ( n + 1) + μ n λ n + μ n a ( n − 1) Recursively, this can be written as. http://home.iitk.ac.in/~skb/qbook/Slide_Set_2.PDF
WebThe birth–death process (or birth-and-death process) is a special case of continuous-time Markov process where the state transitions are of only two types: "births", which increase the state variable by one and "deaths", which decrease the state by one. It was introduced by William Feller. [1] Web2.1. The process starting from Z(0) = n The birth–death process is an example of a Markov branching process in which individuals behave independently; the process starting from n individuals behaves as the sum of n inde-pendent copies of the process starting from a single individual. This shows that the extinction
