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…

Cross-sectional C*-algebras associated to subgroups

Damián Ferraro

Given a Fell bundle over a locally compact and Hausdorff group and a closed subgroup we construct quotients $C^*_{H\uparrow \mathca…

Nuclearity for partial crossed products by exact discrete groups

Alcides Buss, Damián Ferraro, Camila F. Sehnem

We study partial actions of exact discrete groups on C*-algebras. We show that the partial crossed product of a commutative C*-algebra by an exact discrete group is nuclear wheneve…

Fixed point algebras for weakly proper Fell bundles

Damián Ferraro

We define weakly proper Fell bundles and construct exotic fixed point algebras for such bundles. Three alternative constructions of such algebras are given. Under a kind of freenes…

Induction, absorption and weak containment of *-representations of Banach *-algebraic bundles

Damián Ferraro

Given a Fell bundle over a LCH group and a closed subgroup we show that all the *-representations of …

Amenability and approximation properties for partial actions and Fell bundles

Fernando Abadie, Alcides Buss, Damián Ferraro

Building on previous papers by Anantharaman-Delaroche (AD) we introduce and study the notion of AD-amenability for partial actions and Fell bundles over discrete groups. We prove t…

Morita enveloping Fell bundles

Fernando Abadie, Alcides Buss, Damián Ferraro

We introduce notions of weak and strong equivalence for non-saturated Fell bundles over locally compact groups and show that every Fell bundle is strongly (resp. weakly) equivalent…

Equivalence of Fell bundles over groups

Fernando Abadie, Damián Ferraro

We give a notion of equivalence for Fell bundles over groups, not necessarily saturated nor separable, and show that equivalent Fell bundles have Morita-Rieffel equivalent cross-se…

Applications of ternary rings to -algebras

Fernando Abadie, Damián Ferraro

We show that there is a functor from the category of positive admissible ternary rings to the category of -algebras, which induces an isomorphism of partially ordered sets 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…

Construction of enveloping actions

Damián Ferraro

We study the problem of constructing a globalization for partial actions on *-algebras, C*-algebras and Hilbert modules. For the first ones we give a necessary condition for the ex…
