DESCRIPTION:Title: Critical branching random walk in Z^d\n\nAbstract: We c
 onsider a discrete-time branching simple random walk in Z^d where each par
 ticle 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.
  When d=2\, we study the asymptotic behaviors of the critical branching ra
 ndom walk (CBRW) conditioned to survival at large time n and obtain asympt
 otics for local statistics\, range\, 1-multiplicity range etc. We will als
 o discuss some open problems. This is based on the joint walk with Tianyi 
 Bai (AMSS) and Shen Lin (Sorbonne University).
