Abstract
In this paper, we show that a Galton-Watson tree conditioned to have a fixed number of particles in generation converges in distribution as , and with this tool we study the span and gap statistics of a branching random walk on such trees, which is the discrete version of Ramola, Majumdar and Schehr 2015, generalized to arbitrary offspring and displacement distributions with moment constraints.
