WebDeflation is a well-known technique to accelerate Krylov subspace methods for solving linear systems of equations. In contrast to preconditioning, in deflation methods singular systems have to be solved. The original system is multiplied by a projection which leads to a singular linear system which can be more favorable for a Krylov subspace method.
