Abstract: Let M1 and M2 be two Kähler manifolds. Following [4] one says that M1 and M2 are relatives if they share a non-trivial Kähler submanifold S, namely, if there exist two holomorphic and isometric immersions (Kähler immersions) h1 : S → M1 and h2 : S → M2 . Our main results in this paper is Theorem 1.2 where we show that a bounded homogeneous domain with a homogeneous Kähler metric and a projective Kähler manifold (i.e. a projective manifold endowed with the restriction of the Fubini-Study metric) are not relatives. Our result is a generalization of the result obtained in [4] for the Bergman metrics.
