Abstract

Stochastic partial differential equations (SPDE) are derived for the super Brownian motions and Fleming-Viot processes, two important measure-valued processes from population genetics, regarded as distribution function valued processes. The strong uniqueness for the solutions to such type of SPDEs with non-Lipschitz coefficients is obtained by a connection between SPDEs and backward doubly stochastic differential equations.
