2-norm error bounds and estimates for Lanczos approximations to linear systems and rational matrix functions
A. Frommer, K. Kahl, Th. Lippert +1
The Lanczos process constructs a sequence of orthonormal vectors v_m spanning a nested sequence of Krylov subspaces generated by a hermitian matrix A and some starting vector b. In…

Error Bounds for the Sign Function
Andreas Frommer, Karsten Kahl, Thomas Lippert +1
The Overlap operator fulfills the Ginsparg-Wilson relation exactly and therefore represents an optimal discretization of the QCD Dirac operator with respect to chiral symmetry. Whe…
