A generalized BPX multigrid framework covering nonnested V-cycle methods
A generalized BPX multigrid framework covering nonnested V-cycle methods
More than a decade ago, Bramble, Pasciak and Xu developed a framework in analyzing the multigrid methods with nonnested spaces or noninherited quadratic forms. It was subsequently known as the BPX multigrid framework, which was widely used in the analysis of multigrid and domain decomposition methods. However, the framework has …
