Completeness of closed Kleinian flat Pseudo-Riemannian Manifolds of Signature (2,2)

Farid Diaf, Blandine Galiay, Malek Hanounah

Let $R^{2, 2}$ denote the model space of flat pseudo-Riemannian manifolds of signature $(2, 2)$ . We prove that the only domain divisible by a discrete subgroup of the isomet…

On completeness of certain locally symmetric pseudo-Riemannian manifolds of signature $(2, 2)$

Malek Hanounah

We show geodesic completeness of certain compact locally symmetric pseudo-Riemannian manifolds of signature $(2, n)$ . Our model space $X$ is a $1$ -connected, indecomposable…

Completeness of compact Locally symmetric Lorentz manifolds

Souheib Allout, Malek Hanounah

The geodesic completeness of compact locally symmetric Lorentz manifolds has been established in several important cases, namely, the constant curvature, indecomposable, and Brinkm…
