Abstract : 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 depending on geometric quantities, such as the mean curvature and the O-Neill tensor. We then characterize the equality case of the inequality when the ambient manifold is a domain of a Kähler-Einstein manifold or a Riemannian product of a Kähler-Einstein manifold with R or with the circle S^1.

Keywords : Manifolds with boundary spin^c structures Riemannian flows Basic Dirac equation Kähler-Einstein manifolds parallel spinors
