Title: Nonlinear elliptic systems
Author: Defigueiredo, CG
Abstract: In this paper we treat the question of the existence of solutions of boundary value problems for systems of nonlinear elliptic equations of the form -Deltau = f(x, u, v, delu, delv), -Deltav = g(x, u, v, delu, delv), in Ohm, We discuss several classes of such systems using both variational and topological methods. The notion of criticality takes into consideration the coupling, which plays important roles in both a priori estimates for the solutions and Palais-Smale conditions for the associated functional in the variational case.
