A Variational Approach to Subquadratic P
✍ D.G. Costa; C.A. Magalhaes 📂 Article 📅 1994 🏛 Elsevier Science 🌐 English ⚖ 621 KB

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
