A preconditioned MINRES method for optimal control of wave equations and its asymptotic spectral distribution theory
Sean Hon, Jiamei Dong, Stefano Serra-Capizzano
In this work, we propose a novel preconditioned Krylov subspace method for solving an optimal control problem of wave equations, after explicitly identifying the asymptotic spectra…

A sine transform based preconditioned MINRES method for all-at-once systems from constant and variable-coefficient evolutionary PDEs
Sean Hon, Po Yin Fung, Jiamei Dong +1
In this work, we propose a simple yet generic preconditioned Krylov subspace method for a large class of nonsymmetric block Toeplitz all-at-once systems arising from discretizing e…
