Abstract

We show the following theorem: Let X be an irreducible compact Hermitian symmetric manifold of complex dimension n whose bisectional curvature is (s − 1)-nondegenerate. Then in X there exists no smooth Levi-flat CR manifold M with real co-dimension n – s and CR dimension s ≧ 2, such that the determinant ℂ-line bundle of is smoothly trivial.
