Pseudo-Riemannian Lie groups admitting left-invariant conformal vector fields
[Groupes de Lie pseudo-riemanniens admettant des champs vectoriels conformes invariants à gauche]
Comptes Rendus. Mathématique, Volume 358 (2020) no. 2, pp. 143-149.

Soit G un groupe de Lie lorentzien ou un groupe de Lie pseudo-riemannien de type (n-2,2). Si G admet un champ vectoriel invariant à gauche non-Killing, alors G est résoluble.

Let G be a Lorentzian Lie group or a pseudo-Riemannian Lie group of type (n-2,2). If G admits a non-Killing left-invariant conformal vector field, then G is solvable.
