Banach algebras associated to twisted étale groupoids: simplicity and pure infiniteness

Krzysztof Bardadyn, Bartosz Kwaśniewski, Andrew McKee

We define reduced and essential Banach algebras associated to a twisted étale (not necessarily Hausdorff) groupoid $(G, L)$ and extend some fundamental results f…

Topologically free actions and ideals in twisted Banach algebra crossed products

K. Bardadyn, B. K. Kwaśniewski

We generalize the influential $C^{*}$ -algebraic result of Kawamura-Tomiyama and Archbold-Spielberg for crossed products of discrete transformation groups to the realm of Banach algeb…

Banach algebras associated to twisted étale groupoids: inverse semigroup disintegration and representations on $L^{p}$ -spaces

Krzysztof Bardadyn, Bartosz K. Kwaśniewski, Andrew McKee

We introduce Banach algebras associated to twisted étale groupoids $(G, L)$ and to twisted inverse semigroup actions. This provides a unifying framework for nume…
