3-submersions from QR-hypersurfaces of quaternionic Kaehler manifolds
Gabriel Eduard Vilcu
In this paper we study 3-submersions from a QR-hypersurface of a quaternionic Kaehler manifold onto an almost quaternionic hermitian manifold. We also prove the non-existence of qu…
Riemannian submersions from almost contact metric manifolds
Stere Ianus, Adrian Mihai Ionescu, Raluca Mocanu +1
In this paper we obtain the structure equation of a contact-complex Riemannian submersion and give some applications of this equation in the study of almost cosymplectic manifolds…
Conformal Killing-Yano Tensors on Manifolds with Mixed 3-Structures
Stere Ianus, Mihai Visinescu, Gabriel Eduard Vilcu
We show the existence of conformal Killing-Yano tensors on a manifold endowed with a mixed 3-Sasakian structure.
Lightlike real hypersurfaces of paraquaternionic manifolds
Gabriel Eduard Vilcu
The main purpose of this paper is to give fundamental properties of real lightlike hypersurfaces of paraquaternionic manifolds and to prove the non-existence of real lightlike hype…
A note on para-quaternion manifolds
A. M. Ionescu, G. E. Vilcu
We show that a para-quaternion nearly Kahler manifold is necessarily a para-quaternion Kahler manifold
