Supercharacter Theory Constructions Corresponding to Schur Ring Products

Pages 4420-4438 | Received 19 May 2011, Published online: 10 Oct 2012
 

Abstract

Diaconis and Isaacs have defined the supercharacter theories of a finite group to be certain approximations to the ordinary character theory of the group [Citation7]. We make explicit the connection between supercharacter theories and Schur rings, and we provide supercharacter theory constructions which correspond to Schur ring products of Leung and Man [Citation12], Hirasaka and Muzychuk [Citation10], and Tamaschke [Citation20].
