SIAM Journal on Numerical Analysis, Vol. 34, No. 1 (Feb., 1997), pp. 178-200 (23 pages) The purpose of this paper is to develop a convergence theory for multigrid methods applied to nearly singular ...

We describe a new Chebyshev spectral collocation method for systems of variablecoefficient linear delay differential equations with a single fixed delay. Computable uniform a posteriori bounds are ...
