Nuclear Dimension of Twisted $C^{*}$ -Algebras of Virtually Abelian Groups

Forrest Glebe, Pradyut Karmakar, Iason Moutzouris

Let $G$ be a finitely generated virtually abelian group and $[I ¨ ] \in H^{2} (G; T)$ such that $I ¨ (x, y)$ is always a root of unity. We show that the nuclear dimension of the twi…

Continuous categories of endomorphisms associated with $G$ -kernels

Marcel Bischoff, Pradyut Karmakar

We generalize the construction of tensor categories of endomorphisms of a type III factor $M$ associated with a $G$ -kernel, from the case of a discrete group $G$ to that of a compa…

Rapid decay and localizability for Fell bundles over etale Groupoids

Alcides Buss, Pradyut Karmakar

We introduce a notion of the Rapid Decay Property (RDP) for Fell bundles over locally compact Hausdorff Ã©tale groupoids, extending earlier rapid decay theories for Ã©tale groupoid…

FejÃ©r property and Galois correspondence for groupoid $C^{*}$ -algebras

Anshu, Tattwamasi Amrutam, Pradyut Karmakar

We introduce a notion of the FejÃ©r property for topological Ã©tale groupoids. As a consequence, we show that when $G$ is a principal Ã©tale second countable groupoid sat…

Fourier coefficients and rapid decay in reduced groupoid C*-algebras

Adam H. Fuller, Pradyut Karmakar

Let $I^£ \to G$ be a twist over a locally compact Hausdorff Ã©tale groupoid $G$ . Given $f$ in the reduced C $^{*}$ -algebra $C_{r}^{*} (I^£; G)$ with open support $U \subseteq G$ we ask…

Anomalies for conformal nets associated with lattices and $T$ -kernels

Marcel Bischoff, Pradyut Karmakar

Let $L \subseteq R^{n}$ an even lattice and $T_{L} = R^{n} / L$ the associated torus. Associated with $L$ we construct $T_{L}$ --kernel on a hyperfinite factor type $\m…
