Yetter-Drinfeld category for the quasi-Turaev group coalgebra
Published 15 Jul 2015 in math.RA | (1507.04195v1)
Abstract: Let $\pi$ be a group. The aim of this paper is to construct the category of Yetter-Drinfeld modules over the quasi-Turaev group coalgebra $H=({H_\a}_{\a\in\pi},\Delta,\varepsilon,S,\Phi)$, and prove that this category is isomorphic to the center of the representation category of $H$. Therefore a new Turaev braided group category is constructed.
