Eine Bemerkung über homogene Mengen in endlichen Gruppen

Abstract. Let G be a finite group and for each g in G let d(g) be the number of ordered pairs (h,h') in G such that hh'=g. If T is a class of conjugates of G, let d(T)=d(t) for each element in G. Then, there is an explict formula for d(T) in terms of the usual irreducible characters of G.
