The Spike Factorization as Domain Decomposition Method; Equivalent and Variant Approaches


In this paper we present the Spike algorithm of Sameh and Polizzi in the context of domain decomposition methods. We present several variants that differ in their treatment of the separators, showing that one of these is equivalent to the Spike algorithm.
