摘要
In this paper, we study the existence of infinitely many nontrivial solutions for a class of semilinear Schrodinger equations -Delta u + V(x)u = f (x, u), x epsilon R-N, where the primitive of the nonlinearity f is of superquadratic growth near infinity in u and the potential V is allowed to be sign-changing.
