Abstract

Here, we consider a multilevel additive Schwarz (MAS) method which provides the base for the construction of efficient and well parallelizable preconditioners for solving Schur complement interface equations to be considered later on. The terminology was introduced by Dryja and Widlund [55] and goes back to the alternating algorithm proposed by Schwarz [161] in 1870. Due to Xu, this algorithm is also called a parallel subspace correction method. The rigorous analysis of this method may be found in [32, 56, 138, 191].
