Single side birth-death chain of order 2 in random environment is the extension of random walk in random environment
this paper discusses the recurrence
positive recurrence and null recurrence of single side birth-death chain of order 2 in fixed environment and random environment respectively based on the relation between birth-death chain of order 2 and branching chain in time environment
and gives some sufficient and necessary conditions and sufficient conditions.
