Convergence of the age structure of general schemes of population processes
Journal article, 2019
We consider a family of general branching processes with reproduction parameters depending on
the age of the individual as well as the population age structure and a parameter K, which may
represent the carrying capacity. These processes are Markovian in the age structure. In a previous
paper  the Law of Large Numbers as K Ñ 8 was derived. Here we prove the Central Limit
Theorem, namely the weak convergence of the fluctuation processes in an appropriate Skorokhod
space. We also show that the limit is driven by a stochastic partial differential equation.
