Cartan subproduct systems

Suvrajit Bhattacharjee, Olof Giselsson, Sergey Neshveyev

Given a semisimple compact Lie group $G$ and a nonzero dominant integral weight $λ$ , the highest weight $G_{q}$ -modules $V_{nλ}$ form a subproduct system of finite dimensional Hilber…

Quasi-invariant lifts of completely positive maps for groupoid actions

Suvrajit Bhattacharjee, Marzieh Forough

Let $G$ be a locally compact, Hausdorff, second countable groupoid and $A$ be a separable, $C_{0} (G^{(0)})$ -nuclear, $G$ - $C^{*}$ -algebra. We prove the existence of quasi-invariant, com…

Equivariant $C^{*}$ -correspondences and compact quantum group actions on Pimsner algebras

Suvrajit Bhattacharjee, Soumalya Joardar

Let $G$ be a compact quantum group. We show that given a $G$ -equivariant $C^{*}$ -correspondence $E$ , the Pimsner algebra $O_{E}$ can be naturally made into a $G$ -$\m…

Braided quantum symmetries of graph $C^{*}$ -algebras

Suvrajit Bhattacharjee, Soumalya Joardar, Sutanu Roy

We prove the existence of a universal braided compact quantum group acting on a graph $C^{*}$ -algebra in the category of $T$ - $C^{*}$ -algebras with a twisted…
