Drinfeld center of planar algebra
Paramita Das, Shamindra Kumar Ghosh, Ved Prakash Gupta
We introduce fusion, contragradient and braiding of Hilbert affine representations of a subfactor planar algebra (not necessarily having finite depth). We prove that if $N \sub…
Affine modules and the Drinfeld Center
Paramita Das, Shamindra Kumar Ghosh, Ved Prakash Gupta
Given a finite index subfactor, we show that the {\em affine morphisms at zero level} in the affine category over the planar algebra associated to the subfactor is isomorphic to th…
Perturbations of planar algebras
Paramita Das, Shamindra Kumar Ghosh, Ved Prakash Gupta
We analyze the effect of pivotal structures (on a 2-category) on the planar algebra associated to a 1-cell as in \cite{Gho08} and come up with the notion of {\em perturbations of p…
