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.
Classification: 57S20, 53C15
Keywords: Lorentzian manifolds, Conformal transformations
