Abstract

We propose algorithms for the construction of AMG (algebraic multigrid) interpolation mappings such that the resulting coarse space will 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 illustrations are also provided.
