Error estimate of the discontinuous Galerkin finite element method for convection-diffusion problems

الملخص EN

This paper presents the theory analysis of the discontinuous Galerkin finite element (DGFE) method with respect to space variables only is applied whereas, time remains continuous oflinear convection – diffusion problem .The properties of the bilinear form A(u,v)(v-elliptic and continuity) of (DGFE), stability are proved and the approximate solution is converges with error of order (h).
