Ground states of nonlinear Schrödinger equations with potentials
2006
In this paper we study the nonlinear Schrodinger equation:
{−Δu+V(x)u=f(x,u),u∈H1(RN).
We give general conditions which assure the existence of ground state solutions. Under a Nehari type condition, we show that the standard Ambrosetti–Rabinowitz super-linear condition can be replaced by a more natural super-quadratic condition.
