Nonzero and positive solutions of a superlinear elliptic system
Mario Zuluaga · Czech digital mathematics library · 2001
summary:In this paper we consider the existence of nonzero solutions of an undecoupling elliptic system with zero Dirichlet condition. We use Leray-Schauder Degree Theory and arguments of Measure Theory. We will show the existence of positive solutions and we give applications to biharmonic equations and the scalar case.
