Rigidity results for Riemannian spin^c manifolds with foliated boundary
Fida Chami, Nicolas Ginoux, Georges Habib +1
Given a Riemannian spin^c manifold whose boundary is endowed with a Riemannian flow, we show that any solution of the basic Dirac equation satisfies an integral inequality dependin…
Spinorially twisted Spin structures, III: CR structures
Rafael Herrera, Roger Nakad, Ivan Tellez
We develop a spinorial description of CR structures of arbitrary codimension. More precisely, we characterize almost CR structures of arbitrary codimension on (Riemannian) manifold…
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…
