A Variational Approach to Subquadratic P

We consider subquadratic perturbations of semilinear elliptic systems which are in variational form. A unified approach to both the cooperative and noncooperative problems is presented and a condition of nonquadraticity at infinity is introduced to treat the resonant cases through minimax techniques
