title = "Deflated Krylov iterations in domain decomposition methods",
abstract = "The paper is dedicated to an experimental evaluation of some coarse grid techniques in the context of additive Schwarz method and Krylov subspace methods. Some theoretical aspects are considered and a few modifications of well-known methods are presented. The choice of a correction operator is also studied. The results indicate that a coarse grid correction approach may accelerate an iterative process if employed sensibly. The paper also presents a comparison of overlapping and coarse grid correction in terms of convergence speed and performance.",
