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.

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.
