Individuals at the origin in the critical catalytic branching random walk

Authors: Topchii, Valentin and Vatutin, Vladimir

A continuous time branching random walk on the lattice $\mathbb{Z}$ is considered in which individuals may produce children at the origin only. Assuming that the underlying random walk is symmetric and the offspring reproduction law is critical we prove a conditional limit theorem for the number of individuals at the origin.
