Norm Bounds for Rational Matrix Functions.
Norm Estimates for Inverses of Vandermonde Matrices.
Numerical experiments with algebraic multilevel preconditioners.
Numerical experiments with parallel orderings for ILU preconditioners.
Numerical stability of the cyclic Richardson iteration.
Numerical study of two sparse AMG-methods
A sparse algebraic multigrid method is studied as a cheap and accurate way to compute approximations of Schur complements of matrices arising from the discretization of some symmetric and positive definite partial differential operators. The construction of such a multigrid is discussed and numerical experiments are used to verify the properties of the method.
