A hybrid two-level weighted Schwartz method for time-harmonic Maxwell equations
Ziyi Li, Qiya Hu
This paper concerns the preconditioning technique for discrete systems arising from time-harmonic Maxwell equations with absorptions, where the discrete systems are generated by NÃ…

A novel coarse space applying to the weighted Schwarz method for Helmholtz equations
Qiya Hu, Ziyi Li
In this paper we are concerned with restricted additive Schwarz with local impedance transformation conditions for a family of Helmholtz problems in two dimensions. These problems…
