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…
