W*-Amenability for Fell bundles over discrete groups
Alcides Buss, Damián Ferraro
We investigate amenability for -Fell bundles over a discrete group , with a focus on its characterization via approximation properties and conditional expectations. Buildin…
The Leavitt inverse semigroup of a separated graph
Pere Ara, Alcides Buss, Ado Dalla Costa
We introduce and study a new inverse semigroup associated to a separated graph , which we call the \emph{Leavitt inverse semigroup}. This semigroup is obtained as a quotient…
Characterizations of amenability for noncommutative dynamical systems and Fell bundles
Alcides Buss, Damián Ferraro
We resolve key open questions regarding approximation properties and their permanence for Fell bundles over locally compact groups. Specifically, we establish the equivalence betwe…
Operator algebras over the p-adic integers -- II
Alcides Buss, Luiz Felipe Garcia, Devarshi Mukherjee
We continue the study of operator algebras over the -adic integers, initiated in our previous work [1]. In this sequel, we develop further structural results and provide new fam…
Fischer's approach to deformation of coactions
Alcides Buss, Siegfried Echterhoff
This paper explores a novel approach to the deformation of -algebras via coactions of locally compact groups, emphasizing Fischer's construction in the context of maximal coac…
Essential groupoid amenability and nuclearity of groupoid C*-algebras
Alcides Buss, Diego Martínez
We give an alternative construction of the essential -algebra of an étale groupoid, along with an ``amenability'' notion for such groupoids that is implied by the nuclearity o…
