Resumen
We consider an elliptic system with linear part depending on two parameters and a sublinear perturbation. We obtain the existence of at least two solutions when the linear part is near resonance. The system is associated with a strongly indefinite functional and the solutions are obtained through saddle point theorem and Galerkin approximation.
