Groupes de réflexions complexes de rang 2 et leur généralisation

In 2007, Achar & Aubert introduced a family of groups called J-groups generalising rank two complex reflection groups. In this talk, I will introduce the notions of complex reflection groups and J-groups and explain the link between these two notions via a Theorem of Achar & Aubert. Moreover, I will expose the existing results on classification of J-groups and present a generalisation of these results.
