On the optimality of shifted Laplacian in the class of expansion preconditioners for the Helmholtz equation
Siegfried Cools, Wim Vanroose
This paper introduces and explores the class of expansion preconditioners EX(m) that forms a direct generalization to the classic complex shifted Laplace (CSL) preconditioner for H…
