Generalizations of Davidson’s Method for Computing Eigenvalues of Sparse Symmetric Matrices

SIAM Journal on Scientific and Statistical Computing, 1986
The method of \textit{E. R. Davidson} [J. Comput. Phys. 17, 87-94 (1975; Zbl 0293.65022)] for computing a few eigenpairs of large sparse symmetric matrices is analyzed as a method for using diagonal preconditioning (i.e. using an approximate inverse).

A hybrid method for the solution of sparse power system matrices on vector computers

38th Midwest Symposium on Circuits and Systems. Proceedings, 2002
This paper describes a methodology for solving a linear system of equations on vector computer. The methodology combines direct and inverse factors. The decomposition and implementation of the direct solution in a CRAY Y-MPZE/232, and the performance results are discussed.

A Golub--Kahan Davidson Method for Accurately Computing a Few Singular Triplets of Large Sparse Matrices

SIAM Journal on Scientific Computing, 2019
Summary: Obtaining high accuracy singular triplets for large sparse matrices is a significant challenge, especially when searching for the smallest triplets. Due to the difficulty and size of these problems, efficient methods must function iteratively, with preconditioners, and under strict memory constraints. In this research, we present a Golub-Kahan

A New Method for Computing $��$-functions and Their Condition Numbers of Large Sparse Matrices

2016
We propose a new method for computing the $ $-functions of large sparse matrices with low rank or fast decaying singular values. The key is to reduce the computation of $ _{\ell}$-functions of a large matrix to $ _{\ell+1}$-functions of some $r$-by-$r$ matrices, where $r$ is the numerical rank of the large matrix in question.
