Zappa-Szép product groupoids and C*-blends
Nathan Brownlowe, David Pask, Jacqui Ramagge +2
We study the external and internal Zappa-Szép product of topological groupoids. We show that under natural continuity assumptions the Zappa-Szép product groupoid is étale if and on…
Dynamical correspondences for Smale spaces
Robin J. Deeley, D. Brady Killough, Michael F. Whittaker
We initiate the study of correspondences for Smale spaces. Correspondences are shown to provide a notion of a generalized morphism between Smale spaces and are a special case of fi…
Fractal spectral triples on Kellendonk's -algebra of a substitution tiling
Michael Mampusti, Michael F. Whittaker
We introduce a new class of noncommutative spectral triples on Kellendonk's -algebra associated with a nonperiodic substitution tiling. These spectral triples are constructed…
