摘要
本文研究具有一类较广泛分支特征的超布朗运动在临近灭绝时的行为。
We start from a super-Brownian motion with the branching mechanism presented by Dawson and Vinogradov. Its behaviour near extinction is studied in this paper and the main result is that the diameter of the support tends to zero almost surely at the time of extinction.
