Pseudo-Conformal actions of semisimple Lie groups
Mehdi Belraouti, Mohamed Deffaf, Abdelghani Zeghib
We consider the pseudo-Riemannian Lichnerowicz conjecture in the homogeneous setting. In particular, we show that any compact connected pseudo-Riemannian manifold on which a se…

On homogeneous holomorphic conformal structures
Mehdi Belraouti, Mohamed Deffaf, Yazid Raffed +1
We study compact complex manifolds admitting a conformal holomorphic Riemannian structure invariant under the action of a complex semi-simple Lie group . We prove that if th…

Asymptotic behavior of Cauchy hypersurfaces in constant curvature space-times
Mehdi Belraouti
We study the asymptotic behavior of convex Cauchy hypersurfaces on maximal globally hyperbolic spatially compact space-times of constant curvature. We generalise the result of [11]…
