| Résume | Finite Weyl groupoids have been introduced as a tool to classify finite dimensional Nichols algebras. However, a Weyl groupoid may be associated to an arbitrary Nichols algebra. A first step towards a classification of infinite dimensional Nichols algebras is perhaps to understand Weyl groupoids with an infinite root system or more generally infinite reflection groupoids. In this talk, we report on infinite simplicial arrangements and about first classification result |
