Dynamics in large scale geometry
Bruno de Mendonça Braga, Alcides Buss, Ruy Exel
We investigate the large scale geometry of certain metric spaces through the lens of dynamics. Our approach establishes a close connection between large scale dynamical phenomena a…

Consonant inverse semigroups
Ruy Exel
We study necessary and sufficient conditions for two inverse semigroups to possess identical tight groupoids from the point of view of their algebraic, topological, and spectral or…

Flows on uniform Roe algebras
Bruno de Mendonça Braga, Alcides Buss, Ruy Exel
For a uniformly locally finite metric space , we investigate \emph{coarse} flows on its uniform Roe algebra , defined as one-parameter groups of automorp…
