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…
Fourier--Stieltjes category for twisted groupoid actions
Alcides Buss, Bartosz Kwaśniewski, Andrew McKee +1
We extend the theory of Fourier--Stieltjes algebras to the category of twisted actions by étale groupoids on arbitrary C*-bundles, generalizing theories constructed previously by B…
Inverse semigroups of separated graphs and associated algebras
Pere Ara, Alcides Buss, Ado Dalla Costa
In this paper we introduce an inverse semigroup associated to a separated graph and describe its internal structure. In particular we show that it is str…
Operator algebras over the p-adic integers
Alcides Buss, Luiz Felipe Garcia, Devarshi Mukherjee
We introduce -adic operator algebras, which are nonarchimedean analogues of -algebras. We demonstrate that various classical examples of operator algebras - such as group(o…
Deformation of Fell bundles
Alcides Buss, Siegfried Echterhoff
In this paper we study deformations of -algebras that are given as cross-sectional -algebras of Fell bundles over locally compact groups . Our deformation comes from a…
