A proof of the persistence criterion for a class of superprocesses
Published online by Cambridge University Press: 14 July 2016
Abstract
Gorostiza and Wakolbinger (1991), and Dawson and Perkins (1991) established the same persistence criterion for a class of critical branching particle systems and for a class of superprocesses respectively. In this note we take another approach to the criterion and present a simpler proof of it.
