报告题目:Limit theorems for a supercritical two-type decomposable branching process in a random environment.
报告摘要:Let be a two-type decomposable branching process in an independent and identically distributed random environment, where a type 1 particle may produce particles of types 1 and 2,while a type 2 particle can only give birth to type 2 particles. We consider asymptotic properties of this process in the supercritical case. Because
is an usual single-type branching process in a random environment, we only consider
, first, under some moment conditions, we find a suitable factor II, such that the normalized population size
converges almost surely to a finite random variable
, and provide a decomposition expression and a non-degeneracy condition of
. Second, we give conditions under which
is convergent in
for
, and bounded in
for
. Finally, we establish a central limit theorem for
.
