摘要：
We consider the supercritical super-Brownian motion with a general branching mechanism, where particles move as Brownian motion with drift -rho and are killed when they reach the origin. We obtain a large-time asymptotic formula for the survival probability.(c) 2022 Elsevier B.V. All rights reserved.
