Ground state solutions for periodic discrete nonlinear Schrödinger equations with saturable nonlinearities

Abstract In this paper, we study a class of periodic discrete nonlinear Schrödinger equations with asymptotically linear nonlinearities, and prove the existence of ground state solutions (i.e., nontrivial solutions with the least possible energy) by the linking theorem directly. By weakening some co...
