On the Spectral Clustering in Algebraic Multigrid Methods
Jose Pablo Lucero Lorca, Conor McCoid, Michal Outrata
We introduce a new direct multilevel method for solving arbitrary complex square linear systems that uses a regular smoother and an arbitrary but equal number of pre- and post-smoo…

On an efficient line smoother for the p-multigrid γ-cycle
José Pablo Lucero Lorca, Duane Rosenberg, Isidora Jankov +2
As part of the development of a Poisson solver for the spectral element discretization used in the GeoFluid Object Workbench (GeoFLOW) code, we propose a solver for the linear syst…
