An elliptic system modeling two subpopulations. (English) Zbl 1388.92031

Summary: In this paper we study an elliptic system modeling two subpopulations of the same species competing for resources. We show the existence and uniqueness of coexistence states of the system by giving necessary and sufficient conditions.
