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…
Spectral geometry of Riemannian Legendre foliations
Gabriel Baditoiu, Stere Ianus, Anna Maria Pastore
We obtain geometric characterizations of isospectral minimal Riemannian Legendre foliations on compact Sasakian manifolds of constant -sectional curvature.
Paraquaternionic CR-submanifolds of paraquaternionic Kahler manifolds and semi-Riemannian submersions
Stere Ianus, Stefano Marchiafava, Gabriel Eduard Vilcu
In this paper we introduce paraquaternionic CR-submanifolds of almost paraquaternionic hermitian manifolds and state some basic results on their differential geometry. We also stud…
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.
Foliations on quaternion CR-submanifolds
Stere Ianus, Adrian Mihai Ionescu, Gabriel Eduard Vilcu
The purpose of this paper is to study the canonical foliations of a quaternion CR-submanifold of a quaternion Kähler manifold.
Some constructions of almost para-hyperhermitian structures on manifolds and tangent bundles
Stere Ianus, Gabriel Eduard Vilcu
In this paper we give some examples of almost para-hyperhermitian structures on the tangent bundle of an almost product manifold, on the product manifold , where…
A Cohomology (p+1) Form Canonically Associated with Certain Codimension-q Foliations on a Riemannian Manifold
Gabriel Baditoiu, Richard H. Escobales, Stere Ianus
Let be a closed, connected, oriented, , Riemannian, n-manifold with a transversely oriented foliation $\boldkey F$. We show that if ar…
Semi-Riemannian submersions with totally umbilic fibres
Gabriel Baditoiu, Stere Ianus
We get obstructions to existence of semi-Riemannian submersions with totally umbilic fibres.
Semi-Riemannian submersions with totally umbilic fibres
Gabriel Baditoiu, Stere Ianus
We get obstructions to existence of semi-Riemannian submersions with totally umbilic fibres.
Semi-Riemannian submersions from real and complex pseudo-hyperbolic spaces
Gabriel Baditoiu, Stere Ianus
We classify the semi-Riemannian submersions from a pseudo-hyperbolic space onto a Riemannian manifold under the assumption that the fibres are connected and totally geodesic. Also…
