Quantum double inclusions associated to a family of Kac algebra subfactors
Sandipan De
In \cite{Sde2018} we defined the notion of \textit{quantum double inclusion} associated to a finite-index and finite-depth subfactor and studied the quantum double inclusion associ…

From a Kac algebra subfactor to Drinfeld double
Sandipan De
Given a finite-index and finite-depth subfactor, we define the notion of \textit{quantum double inclusion} - a certain unital inclusion of von Neumann algebras constructed from the…
