An Obata-type characterization of Calabi metrics on line bundles
Nicolas Ginoux, Georges Habib, Mihaela Pilca +1
We characterize those complete K{ä}hler manifolds supporting a nonconstant real-valued function with critical points whose Hessian is complex linear, has pointwise two eigenvalues…
An Obata-type characterization of doubly-warped product K\''ahler manifolds
Nicolas Ginoux, Georges Habib, Mihaela Pilca +1
We give a characterization {\sl à la Obata} for certain families of K\''ahler manifolds. These results are in the same line as other extensions of the well-known Obata's rigidity t…
Rigidity results for spin manifolds with foliated boundary
Fida El Chami, Nicolas Ginoux, Georges Habib +1
In this paper, we consider a compact Riemannian manifold whose boundary is endowed with a Riemannian flow. Under a suitable curvature assumption depending on the O'Neill tensor of…
The Energy-Momentum tensor on low dimensional $\Spinc$ manifolds
Georges Habib, Roger Nakad
On a compact surface endowed with any $\Spinc$ structure, we give a formula involving the Energy-Momentum tensor in terms of geometric quantities. A new proof of a Bär-type inequal…
