Abstract
The domain reduction method uses a finite group of symmetries of a system of linear equations arising by discretization of partial differential equations to obtain a decomposition into independent subproblems, which can be solved in parallel. This paper develops a theory for this class of methods based on known results from group representation theory and algebras of finite groups. The main theoretical result is that if the problem splits into subproblems based on isomorphic subdomains, then the group of symmetries must be commutative. General decompositions are then obtained by nesting decompositions based on commutative groups of symmetries.
Zusammenfassung
Das Gebietszerlegungsverfahren verwendet eine endliche Symmetriegruppe des linearen Gleichungssystems, das bei der Diskretisierung von partiellen Differentialgleichungen entsteht, zur Erzeugung einer Zerlegung in unabhängige Teilprobleme, die parallel gelöst werden können. In dieser Arbeit entwickeln wir eine Theorie für diese Verfahrenskalsse, die sich auf Ergebnisse der Darstellungstheorie und der Algebra endlicher Gruppen stützt. Unser zentrales theoretisches Resultat besagt, daß die Symmetriegruppe kommutativ ist, wenn das Problem in Teilprobleme auf isomorphen Teilgebieten zerlegbar ist. Allgemeine Zerlegungen erhält man dann durch geschachtelte Zerlegungen auf Grund von kommutativen Symmetriegruppen.
