摘要：We prove that the uniform spanning forest associated with the biased random walk on d-dimensional integer lattice has finitely many trees if and only if d<4; which is a novel phase transition phenomenon. The talk is based on a joint work with Vladas Sidoravicius (NYU-Shanghai), Zhan Shi (Paris VI Univ.), He Song (宋贺, 泰州银河娱乐场 ) and Longmin Wang (王龙敏, 南开大学).
