Ground and bound states of periodic Schrodinger equations with super or asymptotically linear terms

Qingfang Wu, Dongdong Qin

Abstract:
This paper is concerned with existence of ground and bound states for a class of nonlinear Schrodinger equation with periodic potential. We impose general assumptions on the nonlinearity with super or asymptotically linear growth, and find some refinements of known results and new results by using the perturbation method and a mountain pass argument. In particular, a critical point theory is established for the asymptotically linear growth case.
