In this paper the author presents an a posteriori error estimator for approximations of the solution to an advectiondiffusion equation with a non-constant, vector-valued diffusion coefficient e in a conforming finite element space. Based on the complementary variational principle, we show that the e

Operator or time splitting is often used in the numerical solution of initial boundary value problems for di erential equations. It is, for example, standard practice in computational air pollution modelling where we encounter systems of three-dimensional, time-dependent partial di erential equation

The bilinear finite element methods on appropriately graded meshes are considered both for solving singular and semisingular perturbation problems. In each case, the quasi-optimal order error estimates are proved in the -weighted H 1 -norm uniformly in singular perturbation parameter , up to a logar
