Abstract : We consider a nonuniformly nonlinear elliptic systems with resonance part and nonlinear Neumann boundary condition on an unbounded domain. Our arguments are based on the minimum principle and rely on a generalization of the Landesman-Lazer type condition.
Keywords : semilinear elliptic equation, non-uniform, Landesman-Lazer condition, minimum principle
