Integrability of dual coactions on Fell bundle C*-algebras
Alcides Buss
We study integrability for coactions of locally compact groups. For abelian groups, this corresponds to integrability of the associated action of the Pontrjagin dual group. The the…
A higher category approach to twisted actions on C*-algebras
Alcides Buss, Chenchang Zhu, Ralf Meyer
C*-algebras form a 2-category with \Star{}homomorphisms or correspondences as morphisms and unitary intertwiners as 2-morphisms. We use this structure to define weak actions of 2-c…
Non-Hausdorff Symmetries of C*-algebras
Alcides Buss, Chenchang Zhu, Ralf Meyer
Symmetry groups or groupoids of C*-algebras associated to non-Hausdorff spaces are often non-Hausdorff as well. We describe such symmetries using crossed modules of groupoids. We d…
Fell bundles over inverse semigroups and twisted etale groupoids
Alcides Buss, Ruy Exel
Given a saturated Fell bundle A over an inverse semigroup S which is semi-abelian in the sense that the fibers over the idempotents of S are commutative, we construct a twisted eta…
