Semi-Invariant Riemannian Submersions with Semi-Symmetric Non-Metric Connection

open access: diamondJournal of New Theory, 2021
In this paper, we investigate semi-invariant Riemannian submersion from a Kaehler manifold with semi-symmetric non-metric connection to a Riemannian manifold. We study the geometry of foliations with semi-symmetric non-metric connection.

DDVV-type inequality for skew-symmetric matrices and Simons-type inequality for Riemannian submersions [PDF]

open access: green, 2013
In this paper, we will first derive a DDVV-type optimal inequality for real skew-symmetric matrices, then we apply it to establish a Simons-type integral inequality for Riemannian submersions with totally geodesic fibres and Yang-Mills horizontal ...

Classification of Pseudo-Riemannian submersions with totally geodesic fibres from pseudo-hyperbolic spaces [PDF]

open access: green, 2012
We classify pseudo-Riemannian submersions with connected totally geodesic fibres from a real pseudo-hyperbolic space onto a pseudo-Riemannian manifold. Also, we obtain the classification of the pseudo-Riemannian submersions with (para-)complex connected ...

Riemannian submersions from almost contact metric manifolds

open access: yesAbhandlungen Aus Dem Mathematischen Seminar Der Universitat Hamburg, 2011
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 with Kaehler fibres.Comment: Abh. Math. Semin. Univ.

Biharmonic Riemannian submersions [PDF]

open access: yesAnnali di Matematica Pura ed Applicata (1923 -), 2018
In this paper, we study biharmonic Riemannian submersions. We first derive bitension field of a general Riemannian submersion, we then use it to obtain biharmonic equations for Riemannian submersions with $1$-dimensional fibers and Riemannian submersions with basic mean curvature vector fields of fibers.
