Abstract
(English)
We develop the a priori error analysis of a finite element approximation to a linear elliptic advection-diffusion equation based on the use of residual-free bubble functions. An optimal order error bound is derived in the so-called stability-norm.
Subject Finite element methods, advection-diffusion equations
