Computing finite Weyl groupoids
Iván Angiono, Iván Angiono, Leandro Vendramin
We present algorithms to compute generalized root systems of Nichols algebras of diagonal type and of contragredient Lie superalgebras. As a consequence, we obtain an algorithm to…

Zestings of Hopf Algebras
Iván Angiono, César Galindo, Giovanny Mora
We extend the previously established zesting techniques from fusion categories to general tensor categories. In particular we consider the category of comodules over a Hopf algebra…
