On C*-Algebras Associated to Certain Endomorphisms of Discrete Groups

Published: May 9, 2002
Keywords: endomorphisms, crossed products
Subject: 46L55

Let α:G → G be an endomorphism of a discrete amenable group such that [G:α(G)]<∞. We study the structure of the C* algebra generated by the left convolution operators acting on the left regular representation space, along with the isometry of the space induced by the endomorphism.
