Description:
Title: Preconditioning in H(curl) and H(div)
Abstract: Preconditioning is widely used for efficiently solving large-scale systems of linear equations. In the first part of my talk, I will present a novel application of preconditioning and derive a posteriori error estimates of finite element methods in H(curl) and H(div) using preconditioning theory. In the second part, I will show new user-friendly preconditioners for solving discrete H(curl) and H(div) systems on triangulated surfaces. Part of this talk is based on joint work with Ludmil Zikatanov.
