On positive solutions of general nonlinear elliptic symbiotic interacting systems. (English) Zbl 0757.35023
Summary: After explaining the background of the general symbiotic interactions, we give the sufficient and necessary conditions for the existence of positive solutions to the general elliptic symbiotic models of Dirichlet problem. The result is that such existence of positive solution is characterized by the positive constant equilibria of this system. We also prove that there could be any number of solutions to the symbiotic systems as a result of a singular perturbation of the generators of \(C_ 0\)-semigroup in Banach spaces.
