Abstract
The main goal of this paper is to derive some sufficient conditions for testing the absorption, explosion, and nonexplosion of time-inhomogeneous Markov chains with a countable state space. The method of Lyapunov functions is used for this purpose. Several theorems concerned with such sufficient conditions are proved for a general class of Markov chains. Then they are applied to some problems in time-inhomogeneous birth-death processes and branching processes.
