Journal ArticleDOI
A note on MGR methods
TL;DR: In this paper, a class of special, highly efficient multigrid methods for solving h-discrete elliptic differential equations is introduced, which are characterized by intermediate grids (between the given h-grid and the 2h-grid) and by special fine-to-coarse and coarse-tofine grid transfer techniques.
Book ChapterDOI
Non-standard multigrid techniques using checkered relaxation and intermediate grids
TL;DR: In this paper, the authors examined the nonstandard multigrid (MG) techniques using checkered relaxation and intermediate grids and found that MG-CH-1 and MGR-CH -CH-2 are the most efficient methods.
Book ChapterDOI
Efficient solution of a nonlinear heat conduction problem by use of fast elliptic reduction and multigrid methods
TL;DR: It is shown that the use of a special Multigrid Solver in connection with the time step size control yields a very efficient composite algorithm.
Journal ArticleDOI
On faces and W-irreducible operators in finite-dimensional linear spaces
Ulrich Trottenberg,Gerd Winter +1 more
TL;DR: In this paper, the theoretical relations between the concept of W -irreducibility (Schroder [11]) and those statements in Vandergraft [14] which rely on the notion of faces and the noninvariance properties of irreducible operators are clarified.
