Abstract: In this talk, we propose a pair of interacting stochastic partial differential equations (abbr. SPDEs) with space-time branching noises, which corresponds to a model of two species competitive stochastic
Lotka-Volterra system. We establish the weak solution of the pair of SPDEs through a heuristic approximation from a sequence of pure jump
birth-death Markov processes with branching components.
