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…

Pseudo-Conformal Actions of the M{ö}bius Group
Mehdi Belraouti, Mohamed Deffaf, Yazid Raffed +1
We study compact connected pseudo-Riemannian manifolds on which the conformal group acts essentially and transitively. We prove, in particular, t…
