Firstly, the difference scheme is established for the problem. Then stability of the difference scheme is given and the error analysis for this scheme is evaluated. Finally, the covergence according to the functional of the difference approximation is proved.}, number={2}, publisher={Ağrı İbrahim Çeçen University}
