Contact-Complex Riemannian Submersions [PDF]

open access: yesMathematics, 2021
A submersion from an almost contact Riemannian manifold to an almost Hermitian manifold, acting on the horizontal distribution by preserving both the metric and the structure, is, roughly speaking a contact-complex Riemannian submersion. This paper deals

Biharmonic curves along Riemannian submersions

open access: yesMiskolc Mathematical Notes, 2023
The purpose of this paper is to study biharmonic curves along Riemannian submersions. We first consider a Riemannian submersion from a Riemannian manifold onto Riemannian manifold and investigate under what conditions a biharmonic curve on the total ...

Slant Riemannian submersions from Sasakian manifolds

open access: yesArab Journal of Mathematical Sciences, 2016
We introduce and characterize slant Riemannian submersions from Sasakian manifolds onto Riemannian manifolds. We survey main results of slant Riemannian submersions defined on Sasakian manifolds.

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.

On Quasi Hemi-Slant Submersions

open access: yesCommunications in Advanced Mathematical Sciences, 2023
The paper deals with the notion of quasi hemi-slant submersions from Lorentzian para Sasakian manifolds onto Riemannian manifolds. These submersions are generalization of hemi-slant submersions and semi-slant submersions. In this paper, we also study the

Quasi bi-slant submersions in contact geometry

open access: yesCubo, 2022
The aim of the paper is to introduce the concept of quasi bi-slant submersions from almost contact metric manifolds onto Riemannian manifolds as a generalization of semi-slant and hemi-slant submersions.

Anti-Invariant Lorentzian Submersions From Lorentzian Concircular Structure Manifolds

open access: yesFrontiers in Physics, 2022
This research article attempts to investigate anti-invariant Lorentzian submersions and the Lagrangian Lorentzian submersions (LLS) from the Lorentzian concircular structure [in short (LCS)n] manifolds onto semi-Riemannian manifolds with relevant non ...

Isotropic Riemannian submersions

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2020
Summary: In this paper, we present the notion of isotropic submersions between Riemannian manifolds. We first give examples to illustrate this new notion. Then we express a characterization in terms of O'Neill's tensor field T and examine certain relations between sectional curvatures of the total manifold and the base manifold. We also study \(\lambda\

Pointwise hemi-slant Riemannian submersions

open access: yesUkrains’kyi Matematychnyi Zhurnal, 2023
UDC 517.98 We introduce a new type of submersions, which is called <em>pointwise hemi-slant Riemannian submersions,</em> as a generalization of slant Riemannian submersions, hemi-slant submersions, and pointwise slant submersions from Kaehler manifolds onto Riemannian manifolds.
