Conformal Actions on Homogeneous Lorentzian Manifolds
Journal of Lie Theory, Volume 20 (2010) no. 3, pp. 469-481
A conformal group action on a pseudo-Riemannian manifold is essential if the action is not an isometric action with respect to a conformally equivalent metric. We classify all essential actions of simple Lie groups on Riemannian, Lorentzian and sub-Lorentzian manifolds.
