The Jacobi-Davidson Method for Eigenvalue Problems and its Relation with Accelerated Inexact Newton Schemes

, 1996
. We discuss a new method for the iterative computation of a portion of the spectrum of a large sparse matrix. The matrix may be complex and non-normal. The method also delivers the Schur vectors associated with the computed eigenvalues. The eigenvectors

Restoration of Atmospherically Blurred Images by Symmetric Indefinite Conjugate Gradient Techniques

, 1996
We consider an ill-posed deconvolution problem from astronomical imaging with a given noise-contaminated observation, and an approximately known convolution kernel.

An Implementation of the Look-Ahead Lanczos Algorithm for Non-Hermitian Matrices

, 1991
. The nonsymmetric Lanczos method can be used to compute eigenvalues of large sparse non-Hermitian matrices or to solve large sparse non-Hermitian linear systems. However, the original Lanczos algorithm is susceptible to possible breakdowns and potential

A Unified Deflating Subspace Approach for Classes of Polynomial and Rational Matrix Equations

, 2000
A unified deflating subspace approach is presented for the solution of a large class of matrix equations, including Lyapunov, Sylvester, Riccati and also some higher order polynomial matrix equations including matrix m-th roots and matrix sector ...
