On freely generated semigraph $C^*$-algebras

Operator Algebras 2013-06-24 v2

Abstract

For special universal CC^*-algebras associated to kk-semigraphs we present the universal representations of these algebras, prove a Cuntz--Krieger uniqueness theorem, and compute the KK-theory. These CC^*-algebras seem to be the most universal Cuntz--Krieger like algebras naturally associated to kk-semigraphs. For instance, the Toeplitz Cuntz algebra is a proper quotient of such an algebra.
