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.
