分支依赖于人口总数的具有交互作用的超布朗运动

分支依赖于人口总数的具有交互作用的超布朗运动

In this paper,we investigate the interacting super-Brownian motion depending on population size.This process can be viewed as the high density limit of a sequence of particle systems with branching mechanism depending on their population size.We will construct a limit function-valued dual process.
