Multiplicity of solutions for gradient systems

HISENSE PureFlat RF540N4WI1 Fridge Freezer - Stainless Steel We establish the existence of nontrivial solutions for an elliptic system which is resonant both at the origin and at infinity.The resonance is given by an eigenvalue problem with indefinite weight, and the nonlinear term is permitted to be unbounded.Also, we consider the case where the r
