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…

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…

An Imprimitivity Theorem for Partial Actions
Damián Ferraro
We define proper, free and commuting partial actions on upper semicontinuous bundles of algebras. With such, we construct the algebra induced by a partial action and a…
