Numerical determination of partial spectrum of Hermitian matrices using a Lanczos method with selective reorthogonalization

Chris Johnson, A. D. Kennedy

We introduce a new algorithm for finding the eigenvalues and eigenvectors of Hermitian matrices within a specified region, based upon the LANSO algorithm of Parlett and Scott. It u…

Bounds on the convergence of Ritz values from Krylov subspaces to interior eigenvalues of Hermitean matrices

Chris Johnson, A. D. Kennedy

We consider bounds on the convergence of Ritz values from a sequence of Krylov subspaces to interior eigenvalues of Hermitean matrices. These bounds are useful in regions of low sp…
