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…

Cartan subproduct systems

Suvrajit Bhattacharjee, Olof Giselsson, Sergey Neshveyev

Given a semisimple compact Lie group $G$ and a nonzero dominant integral weight $I^»$ , the highest weight $G_{q}$ -modules $V_{n I^»}$ form a subproduct system of finite dimensional Hilb…
