On $C^*$-algebras Associated to Certain Endomorphisms of Discrete Groups

Authors

Description

Let α:G --> G be an endomorphism of a discrete amenable group such that [G:α(G)]<infinity. 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.
