Two Algorithms For Symmetric Linear Systems With Multiple Right-Hand Sides

, 1998
In this paper, we investigate the block Lanczos algorithm for solving large sparse symmetric linear systems with multiple right-hand sides, and show how to incorporate deflation to drop converged linear systems using a natural convergence criterion, and ...

ABLE: an Adaptive Block Lanczos Method for Non-Hermitian Eigenvalue Problems

, 1995
. This work presents an Adaptive Block Lanczos method for large scale non-Hermitian Eigenvalue problems (henceforth the ABLE method). The ABLE method is a block version of the non-Hermitian Lanczos algorithm. There are three innovations.

Mesh Independence of Matrix-Free Methods for Path Following

, 1998
. In this paper we consider a matrix-free path following algorithm for nonlinear parameter-dependent compact fixed point problems. We show that if these problems are discretized so that certain collective compactness and strong convergence properties ...
