Expansive systems on lattices
Mauricio Achigar
We study expansive dynamical systems in the setting of distributive lattices and their automorphisms, the usual notion of expansiveness for a homeomorphism of a compact metric spac…

A note on Anosov homeomorphisms
Mauricio Achigar
For an -expansive homeomorphism of a compact space we give an elementary proof of the following well-known result in topological dynamics: A sufficient condition for the homeomo…

Cuntz-Pimsner C*-algebras and crossed products by Hilbert C*-bimodules
Beatriz Abadie, Mauricio Achigar
Given a correspondence X over a C*-algebra A, we construct a C*-algebra and a Hilbert C*-bimodule over it whose crossed product is isomorphic to the augmented Cuntz-Pimsner C*-alge…
