文摘
By making use of the critical point theory, the existence of periodic solutions for a class of nonlinear difference equations is obtained. The proof is based on the saddle point theorem in combination with variational technique. The problem is to solve the existence of periodic solutions of a class of nonlinear difference equations. Results obtained complement the existing one.
