Abstract: By using  the critical point theory, we prove the existence of the non-trivial solution of the finite difference scheme for the three-point boundary value problem and get the existence result of the numerical correlation solution for the above continuous problem.

Key words:  , critical point theorem, a priori bounded, Green function, convergence, numerical solution
