Bianchi classification

Lie groups: Bianchi classification

This lecture is part of an online graduate course on Lie groups. We give a sketch of the Bianchi classification of the Lie algebras and groups of dimension at most 3. We mention that this is related to the Thurston geometries of 3-manifolds. For the other lectures in the course see ht
