Abstract:
Branching capacity is a set function introduced in [Zhu 2016], recording hitting probability of a set from afar by a branching random walk. In this talk, we study the continuous counterpart of it, the Brownian snake capacity, and the connection between the two concepts. We define Brownian snake capacity as a Choquet capacity on all bounded Borel set in R d , d ≥ 5, and show that under a mild condition, it is the scaling limit of branching capacity. The talk is based on a joint work with Jean-Francois Delmas and Yueyun Hu.
