Preconditioning of Block Tridiagonal Matrices
[OWP-2008-05] (Mathematisches Forschungsinstitut Oberwolfach, 2008-03-09)Preconditioning methods via approximate block factorization for block tridiagonal matrices are studied. Bounds for the resulting condition numbers are given, and two methods for the recursive construction of the approximate ...
