Branching process theory

Webbranching process conditioned on extinction is equivalent to a subcritical one. In the critical case, we consider two simplestspecial cases of the conditioning events of Pakes [12] and show that suitable modifications of the process lead to some universal limit laws independent of the explicit form of the branching mechanism. The analogues of Webcation of continuous-time branching process with immigration, based on the background studied by Yanev [38], Ney and Bran [39]. By applying the main theory in the general Markov process on branching process and some compu-tational techniques we can have the explicit expression of the first passage time and first exit time.

Let X be a random variable with P [ X = j] = p j and ( X n, i) n, i ≥ 1 i.i.d. random variables with X n, i = L X. Then we define the branching process Z n to be the number of individuals in the n-th generation, where, by convention, we let Z 0 = 1.
