The spatial segregation of the populations occurs commonly in ecology. One typical way to understand this phenomenon is consider strong competition some species. In paper, we shall multiple-species competition-diffusion models. Under condition that interspecies rates are large, show occurs. Furthermore, derive two-phase Stefan-like problems appearing as singular limit, which may provide modelin...
