We consider the solution of differential equations with multidelays by using boundary value methods (BVMs). These methods require the solution of some nonsymmetric, large and sparse linear systems. The GMRES method with the Strang-type block-cireulant preconditioner is proposed to solve these linear

## Abstract Implicit difference methods for the wave equation in two space variables have been discussed with the help of a stability diagram. The difference methods of intermediate accuracy 0(__h__^4^+__k__^2^) have been determined. A method of order of accuracy 0(__h__^2^+__k__^2^) with minimum t

In this paper, we consider solving potential equations by the boundary integral equation approach. The equations so derived are Fredholm integral equations of the ΓΏrst kind and are known to be ill-conditioned. Their discretized matrices are dense and have condition numbers growing like O(n) where n
