Abstract

Let α : G → G be an endomorphism of a discrete amenable group such that [G : α(G)] < ∞. We study the structure of the Cz.ast; 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.
