| Abstract: | In this paper,we employed the critical point theory to deal with the existence of solutions for some two-point boundary value problems of second-order nonlinear difference equations and obtain several novel sufficient conditions for the existence of the solution for involved problem.Through our investigation,the research results of this kind were enriched. |
