On the theory of Schur-Rings

Abstract

Diese Arbeit versucht, die von Issai Schur[1] entdcckte und von Wielandt ([14], [15], [16], [17]) betrachtlich neiterentwickelte Methode zur Untersuchung von endlichen Permutationsgruppen zu einer Theorie der Schur-Ringe zu entfalten. Der Grundgedanke ist sehr einfach: Die Schur-Ringe werden nicht als eine spezielle Klasse von Ringen aufgefaβt, sondern als eine eigene mathematische Struktur. Nach unserer heutigen Ansicht fallt der Begriff der mathematischen Struktur weitgehend mit dem Begriff der Kategorie zusammen. Daher wird fur die Schur-Ringe (genauer: fur die Schur-Algebren) ein eigener Homomorphiebegriff (Definition1.5) eingefuhrt, der eine Kategorie liefert (Theorem1.6).
