Positivstellensatz for C*-tensor categories

Kajal Das, Mainak Ghosh, Shamindra Ghosh

We explore semi-pre-C*-algebras in the context of rigid semisimple C*-tensor categories and using techniques from annular representations, we extend Ozawa's criterion for property…

Unitary connections on Bratteli diagrams

Paramita Das, Mainak Ghosh, Shamindra Ghosh +1

In this paper, we extend Ocneanu's theory of connections on graphs to define a 2-category whose 0-cells are tracial Bratteli diagrams, and whose 1-cells are generalizations of unit…

Free oriented extensions of subfactor planar algebras

Shamindra Kumar Ghosh, Corey Jones, B Madhav Reddy

We show that the restriction functor from oriented factor planar algebras to subfactor planar algebras admits a left adjoint, which we call the free oriented extension functor. We…

Annular Representations of Free Product Categories

Shamindra Kumar Ghosh, Corey Jones, B Madhav Reddy

We provide a description of the annular representation category of the free product of two rigid C*-tensor categories.

Tube representations and twisting of graded categories

Jyotishman Bhowmick, Shamindra Ghosh, Narayan Rakshit +1

We study deformation of tube algebra under twisting of graded monoidal categories. When a tensor category is graded over a group , a torus-valued 3-cocycle on …

Tube algebra of group-type subfactors

Dietmar Bisch, Paramita Das, Shamindra Kumar Ghosh +1

We describe the tube algebra and its representations in the cases of diagonal and Bisch-Haagerup subfactors possibly with a scalar 3-cocycle obstruction. We show that these categor…
