Preconditioning and Conditioning of Systems Arising from Boundary Value Methods


The application of Boundary Value Methods to several classes of Differential Equations requires the solution of large dimension and sparse linear systems having (block) quasi-Toeplitz coefficient matrices. This has naturally suggested the use of Krylov subspace methods in combination with well known preconditioners suitable for Toeplitz matrices. However… (More)
