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 ...

Some algorithms based upon a projection process onto the Krylov subspace $K_m = \operatorname{Span}(r_0, Ar_0, \ldots, A^{m - 1}r_0)$ are developed, generalizing the ...
