AF-action groupoid models for diagonal AH-algebras

Ali Imad Raad, Jonathan Taylor

We show that an inductive AH-system with diagonal connecting maps describes an action of the canonical AF-groupoid on the spectrum of the canonical C-diagonal, and that the can…

Limits in categories of étale groupoids and pseudogroups

Jonathan Taylor

We show that the category of sober étale groupoids and actors admits all small limits. This is achieved by computing the limits in the equivalent category of pseudogroups with pseu…

Functoriality for groupoid and Fell bundle -algebras

Jonathan Taylor

We define a class of morphisms between étale groupoids and show that there is a functor from the category with these morphisms to the category of -algebras. We show that all h…

Essential Cartan subalgebras of -algebras

Jonathan Taylor

We define essential commutative Cartan pairs of -algebras generalising the definition of Renault and show that such pairs are given by essential twisted groupoid -algebra…

Inductive Limits of Noncommutative Cartan Inclusions

Ralf Meyer, Ali Imad Raad, Jonathan Taylor

We prove that an inductive limit of aperiodic noncommutative Cartan inclusions is a noncommutative Cartan inclusion whenever the connecting maps are injective, preserve normalisers…

Localised Hilbert modules and weak noncommutative Cartan pairs

Jonathan Taylor

We define the localisation of a Hilbert module in analogy to the local multiplier algebra. We use properties of this localisation to enrich non-closed actions on -algebras to…
