Robust Preconditioning for Space-Time Isogeometric Analysis of Parabolic Evolution Problems
Christoph Hofer, Ulrich Langer, Martin Neumüller
We propose and investigate new robust preconditioners for space-time Isogeometric Analysis of parabolic evolution problems. These preconditioners are based on a time parallel multi…

Time-parallel iterative solvers for parabolic evolution equations
Martin Neumuller, Iain Smears
We present original time-parallel algorithms for the solution of the implicit Euler discretization of general linear parabolic evolution equations with time-dependent self-adjoint…

The auxiliary space preconditioner for the de Rham complex
Jay Gopalakrishnan, Martin Neumüller, Panayot Vassilevski
We generalize the construction and analysis of auxiliary space preconditioners to the n-dimensional finite element subcomplex of the de Rham complex. These preconditioners are base…
