GMRES and the Minimal Polynomial

, 1995
. We present a qualitative model for the convergence behaviour of the Generalised Minimal Residual (GMRES) method for solving nonsingular systems of linear equations Ax = b in finite and infinite dimensional spaces.

Asynchronous Parallel Hybrid GMRES/LSArnoldi Method

, 1998
. Linear algebra problems described by large size sparse matrices require an intensive parallelism as well as appropriate methods. Iterative methods such as GMRES have already proven their efficiency in this case.

On the convergence of GMRES with invariant-subspace deflation

, 2010
We consider the solution of large and sparse linear systems of equations by GMRES. Due to the appearance of unfavorable eigenvalues in the spectrum of the coefficient matrix, the convergence of GMRES may hamper.
