A Two-Level Direct Solver for the Hierarchical Poincaré-Steklov Method

Joseph Kump, Anna Yesypenko, Per-Gunnar Martinsson

We introduce a two-level direct solver for the Hierarchical Poincaré-Steklov (HPS) method for solving linear elliptic PDEs. HPS combines multidomain spectral collocation with a di…
