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…
