Bayesian inference and retrodiction for faithful states on von Neumann algebras

Pradyut Karmakar, Arthur J. Parzygnat

Retrodiction is the act of inferring a cause from its effects, the most common example of which is Bayesian inference. Retrodiction can be defined by its structural process-theoret…

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 $[σ] \in H^{2} (G; T)$ such that $σ (x, y)$ is always a root of unity. We show that the nuclear dimension of the twist…

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 étale groupoids, extending earlier rapid decay theories for étale groupoids…

Fejér property and Galois correspondence for groupoid $C^{*}$ -algebras

Anshu, Tattwamasi Amrutam, Pradyut Karmakar

We introduce a notion of the Fejér property for topological étale groupoids. As a consequence, we show that when $G$ is a principal étale second countable groupoid satisf…

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

Adam H. Fuller, Pradyut Karmakar

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

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…
