| Abstract: |
| This paper studies the existence of solutions for a second order difference boundary value problem. Using critical point theory and variational method, some existence theorems of solutions are established. The results obtained here improve some existing results in the literature. |
| Key words: difference equation variational method critical point theory solution |
