A note on almost co-Kähler manifolds

UC De, SK Chaubey, YJ Suh - International Journal of Geometric …, 2020 - World Scientific
We characterize almost co-Kähler manifolds with gradient Yamabe, gradient Einstein and
quasi-Yamabe solitons. It is proved that if the metric of a (κ, μ)-almost co-Kähler manifold M 2 …

Almost co-Kähler manifolds and (m, ρ)-quasi-Einstein solitons

K De, MNI Khan, UC De - Chaos, Solitons & Fractals, 2023 - Elsevier
The present paper aims to investigate (m, ρ)-quasi-Einstein metrics on almost co-Kähler
manifolds M. It is proven that if a (κ, μ)-almost co-Kähler manifold with κ< 0 is (m, ρ)-quasi …

Gradient Ricci solitons and Fischer–Marsden equation on cosymplectic manifolds

SK Chaubey, GE Vîlcu - Revista de la Real Academia de Ciencias …, 2022 - Springer
The goal of this paper is to investigate the existence of non-trivial solutions for Fischer–
Marsden equation (FME) within the framework of (2 n+ 1)-dimensional cosymplectic …

Minimal and harmonic Reeb vector fields on trans-Sasakian 3-manifolds

Y Wang - Journal of the Korean Mathematical Society, 2018 - koreascience.kr
In this paper, we obtain some necessary and sufficient conditions for the Reeb vector field of
a trans-Sasakian 3-manifold to be minimal or harmonic. We construct some examples to …

Conformal vector fields on almost co-Kähler manifolds

UC De, YJ Suh, SK Chaubey - Mathematica Slovaca, 2021 - degruyter.com
In this paper, we characterize almost co-Kähler manifolds with a conformal vector field. It is
proven that if an almost co-Kähler manifold has a conformal vector field that is collinear with …

Ricci tensors on three-dimensional almost coKähler manifolds

Y Wang - Kodai Mathematical Journal, 2016 - jstage.jst.go.jp
Let M3 be a three-dimensional almost coKähler manifold such that the Ricci curvature of the
Reeb vector field is invariant along the Reeb vector field. In this paper, we obtain some …

Almost co-K\"{a} hler manifolds satisfying some symmetry conditions

Y Wang - Turkish Journal of Mathematics, 2016 - journals.tubitak.gov.tr
Abstract Let $ M^{2n+ 1} $ be an almost co-K\"{a} hler manifold of dimension $> 3$ with
K\"{a} hlerian leaves. In this paper, we first prove that if $ M^{2n+ 1} $ is locally symmetric …

[HTML][HTML] Almost α-paracosymplectic manifolds

IK Erken, P Dacko, C Murathan - Journal of Geometry and Physics, 2015 - Elsevier
This paper is a complete study of almost α-paracosymplectic manifolds. Basic properties of
such manifolds are obtained and general curvature identities are proved. The manifolds with …
