CR relatives Kaehler manifolds

Differential Geometry 2022-06-09 v2

Abstract

In this paper we show that two K\"ahler manifolds which do not share a K\"ahler submanifold, do not share either a Levi degenerate CR-submanifold with constant dimension Levi kernel. In particular, they do not share a CR-product. Further, we obtain that a Levi degenerate CR-submanifold of Cn\mathbb C^n cannot be isometrically immersed into a flag manifold.
