摘要:We consider a discrete-time branching simple random walk in Z^2 where each particle independently makes simple random walk and produces a random number of children so that the offspring law is of mean 1 and of finite variance. We study the asymptotic behaviours of the critical branching random walk (CBRW) conditioned to hit a given site at large time n and obtain a Yaglom theorem. We also discuss the joint survival probabilities that the CBRW hits two sites which are of distances Θ(na) at large time n, as well as the number of occupied sites.
