This paper is devoted to the development of a new stabilized finite element method forsolving the aivection-diffusion equations having the form -κ△ u + a @ V u + σ u = f witha zero Dirichlet boundary condition. We show that this methodology is coercive and hasa uniformly optimal convergence result for all mesh-Peclet number.
