The conformal group of a compact simply connected Lorentzian manifold
Karin Melnick, Vincent Pecastaing
We prove that the conformal group of a closed, simply connected, real analytic Lorentzian manifold is compact. D'Ambra proved in 1988 that the isometry group of such a manifold is…

Projective and conformal closed manifolds with a higher-rank lattice action
Vincent Pecastaing
We prove global results about actions of cocompact lattices in higher-rank simple Lie groups on closed manifolds endowed with either a projective class of connections or a conforma…

Conformal actions of higher rank lattices on compact pseudo-Riemannian manifolds
Vincent Pecastaing
We investigate conformal actions of cocompact lattices in higher-rank simple Lie groups on compact pseudo-Riemannian manifolds. Our main result gives a general bound on the real-ra…
