Horizontally Conformal Submersions from CR-Submanifolds of Locally Conformal Kahler Manifolds

摘要

In this paper, we study horizontally conformal submersions from CR-submanifolds of a locally conformal Kahler manifold onto almost Hermitian manifolds, generalizing the results obtained by Sahin (Kodai Math. J. 31, 2008), for horizontally conformal submersions of CR-submanifolds in Kahler ambient space. In particular, we show that any horizontally homothetic submersion of a CR-submanifold M of a locally conformal Kahler manifold with Lee vector field normal to M is a Riemannian submersion up to a scale. Moreover, we obtain that such a map is harmonic, provided that the CR-submanifold is mixed geodesic.
