Preconditioned Recycling Krylov subspace methods for self-adjoint problems
André Gaul, Nico Schlömer
The authors propose a recycling Krylov subspace method for the solution of a sequence of self-adjoint linear systems. Such problems appear, for example, in the Newton process for s…

A framework for deflated and augmented Krylov subspace methods
André Gaul, Martin H. Gutknecht, Jörg Liesen +1
We consider deflation and augmentation techniques for accelerating the convergence of Krylov subspace methods for the solution of nonsingular linear algebraic systems. Despite some…
