The homology of the groupoid of the self-similar dihedral group
Ortega Esparza, Eduardo; Sanchez, Alvaro (Peer reviewed; Journal article, 2022)We compute the K -theory of the C∗ -algebra associated to the self-similar infinite dihedral group, and the homology of its associated étale groupoid. We see that the rational homology differs from the K -theory, strongly ...
