Submersions involving some special classes of K-manifolds.
Luigia Di Terlizzi, Anna Maria Pastore, Robert A. Wolak

Abstract. We study properties of invariant submanifolds of K-manifolds as well as of some special types of K-manifolds. Moreover, we investigate properties of submersions between f-manifolds. In particular, we find some curvature identities when the total space is an S-manifold and the base space is Kähler
