Time: 3:45pm, Thursday, October 28, 2021 Venue: Clements Hall 126 Title: Direct solvers for elliptic PDEs Speaker: Gunnar Martinsson, Oden Institute, UT Austin Abstract: That the linear systems arising upon the discretization of elliptic PDEs can be solved efficiently is well-known, and iterative solvers that often attain linear complexity (multigrid, Krylov methods, etc) have proven […]
