Abstract: We consider a discrete-time branching simple random walk in Z^d 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. For the branching random walk starting from some far away site x in Z^d conditioned on hitting the origin, we study the asymptotical behaviors of the occupation time at the origin.
