Abstract

For the critical branching random walk in Z4\mathbb{Z}^{4} with branching at the origin only we find the asymptotic behavior of the probability of the event that there are particles at the origin at moment tt\rightarrow \infty and prove a Yaglom type conditional limit theorem for the number of individuals at the origin given that there are particles at the origin.
