The Two-Prime Analogue Of The Hecke C*-Algebra Of Bost And Connes, Nadia Larsen, Ian Putnam, Iain Raeburn
Faculty of Engineering and Information Sciences - Papers: Part A
Let p and q be distinct odd primes. We analyse a semigroup crossed product C * (G p,q) α 2 similar to the semigroup crossed product which models the Hecke C * -algebra of Bost and Connes. We describe a composition series of ideals in C * (G p,q) α 2 , and show that the structure of one of the subquotients reflects interesting number-theoretic information about the multiplicative orders of q in the rings Z/pl Z.
