An efficient relaxed shift-splitting preconditioner for a class of complex symmetric indefinite linear systems
In this work, by introducing a scalar matrix αI, we transform the complex symmetric indefinite linear systems (W+iT)x=b into a block two-by-two complex equations equivalently, and propose an efficient relaxed shift-splitting (ERSS) preconditioner. By adopting the relaxation technique, the ERSS preco...
