Higher Braidings of Diagonal Type

Michael Cuntz, Tobias Ohrmann

Heckenberger introduced the Weyl groupoid of a finite-dimensional Nichols algebra of diagonal type. We replace the matrix of its braiding by a higher tensor and present a construct…

A simplicial complex of Nichols algebras

Michael Cuntz, Simon Lentner

We translate the concept of restriction of an arrangement in terms of Hopf algebras. In consequence, every Nichols algebra gives rise to a simplicial complex decorated by Nichols a…

An isomorphism between the fusion algebras of $V_{L}^{+}$ and type $D^{(1)}$ level 2

Michael Cuntz, Christopher Goff

The fusion algebra of the vertex operator algebra $V_{L}^{+}$ for a rank 1 even lattice $L$ is explicitly shown to be isomorphic to the fusion algebra of the Kac-Moody algebra of type…
