dc.description.abstractA NEW HYBRID MIXED FINITE ELEMENT METHOD IS PROPOSED FOR SOLVING THE CONVECTION-DIFFUSION-REACTION EQUATION WITH LOCAL EXPONENTIAL FITTING TECHNIQUE. IN THIS METHOD, THE EXPONENTIAL FITTING TECHNIQUE IN [7] IS USED TO DISCRETIZE THE CONVECTION-DIFFUSION- REACTION EQUATION BY INTRODUCING A NEW VARIABLE AT ELEMENT LEVEL; THEN THE HYBRID MIXED DISCONTINUOUS GALERKIN FINITE ELEMENT METHOD IS USED TO APPROXIMATE THE DISCRETIZED PROBLEM. THE CONVERGENCE OF THE PROPOSED METHOD IS ANALYZED, AND THE CORRESPONDING A PRIORI ERROR ESTIMATE IS DERIVED. THE NUMERICAL RESULTS ARE PRESENTED TO CONFIRM OUR THEORETICAL ANALYSIS.
