A modular framework for the backward error analysis of GMRES
International audienceThe Generalized Minimal Residual methods (GMRES) for the solution of general square linear systems is a class of Krylov-based iterative solvers for which there exist backward error analyses that guarantee the computed solution in ...

GMRESR: A family of nested GMRES methods
, 1991 Recently Eirola and Nevanlinna have proposed an iterative solution method for unsymmetric linear systems, in which the preconditioner is updated from step to step.

An augmented IIM-level set method for Stokes equations with discontinuous viscosity
Electronic Journal of Differential Equations, 2007 A finite difference method is proposed for incompressible Stokes equations with discontinuous viscosity. The method combines the augmented immersed interface method with a level set representation of the interface on a uniform Cartesian grid.

A New Adaptive GMRES Algorithm for Achieving High Accuracy
, 1996 GMRES(k) is widely used for solving nonsymmetric linear systems. However, it is inadequate either when it converges only for k close to the problem size or when numerical error in the modified Gram-Schmidt process used in the GMRES orthogonalization ...

A fast implementation for GMRES method
, 2003 For the popular iterative method GMRES, we present a new and simple implementation which has the property of not using Givens rotations. This implementation does not modify the Arnoldi process and has an advantage in both the computational effort and the
