A Neutral relation between metallic structure and almost quadratic ϕ-structure
In this paper, we give a neutral relation between metallic structure and almost quadratic metric ?-structure. Considering N as a metallic Riemannian manifold, we show that the warped product manifold R ?f N has an almost ...
Reeb Flow Symmetry on 3-Dimensional Almost Paracosymplectic Manifolds
(Univ Nis, Fac Sci Math, 2019)
Mainly, we prove that the Ricci operator Q of an 3-dimensional almost paracosymplectic manifold M is invariant along the Reeb flow, that is M satisfies L(xi)Q = 0 if and only if M is an almost paracosymplectic kappa-manifold ...
A Generalized Wintgen Inequality for Legendrian Submanifolds in Almost Kenmotsu Statistical Manifolds
Main interest of the present paper is to obtain the generalized Wintgen inequality for Legendrian submanifolds in almost Kenmotsu statistical manifolds.
Almost cosympletic statistical manifolds
(Natl Inquiry Services Centre Pty Ltd, 2020)
This paper is a study of almost contact statistical manifolds. Especially this study is focused on almost cosymplectic statistical manifolds. We obtained basic properties of such manifolds. A characterization theorem and ...
Biharmonic Pseudo-Riemannian Submersions from 3-Manifolds
(Univ Nis, Fac Sci Math, 2018)
We classify the pseudo-Riemannian biharmonic submersion from a 3-dimensional space form onto a surface.
CLASSIFICATION OF THREE-DIMENSIONAL CONFORMALLY FLAT QUASI-PARA-SASAKIAN MANIFOLDS
(Honam Mathematical Soc, 2019)
The aim of this paper is to study three-dimensional conformally flat quasi-para-Sasakian manifolds. First, the necessary and sufficient conditions are provided for three-dimensional quasi-para-Sasakian manifolds to be ...
ON A CLASSIFICATION OF ALMOST α-COSYMPLECTIC MANIFOLDS
(Tusi Mathematical Research Group (TMRG), 2019)
The object of the present paper is to study almost ?-cosymplectic manifolds. We consider projectively flat, conformally flat, and concircularly flat almost ?-cosymplectic manifolds (with the ?-parallel tensor field ?h) and ...
Curvature Properties of Quasi-Para-Sasakian Manifolds
(Int Electronic Journal Geometry, 2019)
The paper is devoted to study quasi-para-Sasakian manifolds. Basic properties of such manifolds are obtained and general curvature identities are investigated. Next it is proved that if M is a quasi-para-Sasakian manifold ...
PARACONTACT METRIC (κ, µ) R-HARMONIC MANIFOLDS
(Univ Kragujevac, Fac Science, 2020)
We give classifications of paracontact metric ((kappa) over tilde,(mu) over tilde) manifolds M2n+1 with harmonic curvature for n > 1 and n = 1.
