✦ Synopsis

Some modi®ed AGE methods for the convection±diusion equation are developed in this paper. Firstly, there is a treatment on the convection term in the equation which is dierent from that in the AGE method by Evans and Abdullah (1985). Secondly, upwind-type schemes are used for the convection dominated diusion problems. All the modi®ed AGE methods in the paper are unconditionally stable. The numerical example is given to show the eectiveness of the methods. The methods have the obvious property of parallelism.

The solution of the linear system Ax = b by iterative methods requires a splitting of the coefficient matrix in the form A = M -N where M is usually chosen to be a diagonal or a triangular matrix. In this article we study relaxation methods induced by the Hermitian and skew-Hermitian splittings for
