Title:GENERALIZED NEHARI MANIFOLD AND SEMILINEAR SCHR?DINGER EQUATION

Abstract We study the Schr?dinger   equations u+ V (x)u = f(x; u) in and

u-λu = f(x; u)in a bounded domain. We assume that f is superlinear but

of subcritical growth and is nondecreasing. In we also assume that V and f are periodic in . We show that these equations have a ground state and that there exist infinitely many solutions if f is odd in u. The results generalize those od Szulkin and Weth, where was assumed to be strictly increasing. This seemingly small change forces us to go beyond methods of smooth analysis. The work is joint with F. de Paiva and A. Szulkin.
