An efficient preconditioner for evolutionary partial differential equations with -method in time discretization
Yuan-Yuan Huang, Po Yin Fung, Sean Y. Hon +1
In this study, the -method is used for discretizing a class of evolutionary partial differential equations. Then, we transform the resultant all-at-once linear system and introd…

Block -circulant preconditioners for parabolic optimal control problems
Po Yin Fung, Sean Hon
In this work, we propose a class of novel preconditioned Krylov subspace methods for solving an optimal control problem of parabolic equations. Namely, we develop a family of block…

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…
