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…
Complex and Lagrangian surfaces of the complex projective plane via Kählerian Killing Spin spinors
Roger Nakad, Julien Roth
The complex projective space of complex dimension has a Spin structure carrying Kählerian Killing spinors. The restriction of one of these Kählerian Killing…
Eigenvalue Estimate for the basic Laplacian on manifolds with foliated boundary, part II
Fida El Chami, George Habib, Ola Makhoul +1
In [4], we gave a sharp lower bound for the first eigenvalue of the basic Laplacian acting on basic -forms defined on a compact manifold whose boundary is endowed with a Riemann…
