Multiple Vector Preserving Interpolation Mappings in Algebraic Multigrid

Journal Article · · SIAM Journal on Matrix Analysis with Applications
OSTI ID:883832
We propose algorithms for the construction of AMG (algebraic multigrid) interpolation mappings such that the resulting coarse space to span (locally and globally) any number of a priori given set of vectors. Specific constructions in the case of element agglomeration AMG methods are given. Some numerical illustration is also provided.
