Domain Decomposition preconditioning for high-frequency Helmholtz problems with absorption

Ivan G. Graham, Euan A. Spence, Eero Vainikko

In this paper we give new results on domain decomposition preconditioners for GMRES when computing piecewise-linear finite-element approximations of the Helmholtz equation $-Δu - (…
