Add to ORKGon his 70th birthday anniversary Abstract. We give some existence results for bounded solutions of linear and nonlinear second order difference equations. In particular, a method of lower and upper solutions for bounded solutions of some nonlinear second order difference equations is obtained, and applied to Duffing-type difference equations
