Title: Competition Exclusion or Coexistence in Spatially Heterogeneous Environment

Abstract: The classical Lotka-Volterra competition model predicts competition exclusion occurs when the competition is strong, and species can coexist when the competition is weak. In a spatially heterogeneous environment, the dispersal rates of species and the spatial heterogeneity could change or uphold the outcome of the competition. We show in several spatially heterogeneous Lotka-Volterra competition models, the coexistence steady state is globally asymptotically stable, while in another case, multiple positive steady states exist.
