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
A variational approch is proposed for the approximate description of decaying states represented by Gamow functions. The method is suited to describing many-particle systems with antisymmetry. It is shown that, in combination with a generator-coordinate basis, its actual application is as feasible a
