Abstract:We construct two kinds of stochastic flows of discrete Galton-Watson branching processes. Some scaling limit theorems for the flows are proved, which lead to local and nonlocal branching superprocesses over the positive half line.
Keywords:Stochastic flow   Galton-Watson branching process   continuous- state branching process   superprocess   nonlocal branching
