报告摘要：We study the particle range of a branching Brownian motion on the Euclidean space.We prove that the upper bound of this range is determinedby the principal eigenvalue of the Schr?dinger type operator associatedwith the branching rate and mechanism.Here the branching rate measure is small enough at infinity, and can be singular with respect to the Lebesgue measure.
