Abstract

Let XX be a connected complex manifold of dimension 3\geq 3 and MM a smooth compact Levi-flat real hypersurface in XX. We show that the normal bundle to the Levi foliation does not admit a Hermitian metric with positive curvature along the leaves. This generalizes a result obtained by Brunella.
