    The existence of homoclinic solutions in periodic nonlinear difference equations with superlinear nonlinearity is considered. The classical Ambrosetti-Rabinowitz superlinear condition is improved by a general superlinear one. The main idea in this paper is an application of a linking theorem combined with an approximation technique.
