Some characterizations of three-dimensional trans-Sasakian manifolds admitting η- Ricci solitons and trans-Sasakian manifolds as Kagan subprojective space

Ukrains’kyi Matematychnyi Zhurnal, 2020
UDC 514.7 The object of the present paper is to study three-dimensional trans-Sasakian manifolds admittingη-Ricci soliton. Actually, we study such manifolds whose Ricci tensor satisfy some special conditions like cyclic parallelity, Ricci semisymmetry,ϕ-Ricci semisymmetry, after reviewing the properties of second order parallel tensors on such ...

Ricci Solitons in f-Kenmotsu Manifolds and 3-dimensional Trans-Sasakian Manifolds

, 2012
In the Present paper we study Ricci solitons in trans-sasakian manifolds. In particular we consider Ricci solitons in f -Kenmotsu manifolds and we prove the conditions for the Ricci solitons to be shrinking, steady and expanding.Key words: Ricci solitons;

A.: On three-dimensional trans-Sasakian manifolds

, 2020
: The object of the present paper is to study 3-dimensional trans-Sasakian manifolds which are locally φ-symmetric and have η-parallel Ricci tensor. Also 3-dimensional transSasakian manifolds of constant curvature have been considered.

Can trans-S-manifolds be defined from the Gray-Hervella classification for almost Hermitian manifolds?

, 2022
Recently, trans-S-manifolds have been defined as a wide class of metric f-manifolds which includes, for instance, f-Kenmotsu manifolds, S-manifolds and C-manifolds and generalize well-studied trans-Sasakian manifolds.

Characterizations of the Total Space (Indefinite Trans-Sasakian Manifolds) Admitting a Semi-Symmetric Metric Connection

Axioms, 2018
We investigate recurrent, Lie-recurrent, and Hopf lightlike hypersurfaces of an indefinite trans-Sasakian manifold with a semi-symmetric metric connection. In these hypersurfaces, we obtain several new results.

A Note on Nearly Sasakian Manifolds

, 2023
A class of nearly Sasakian manifolds is considered in this paper. We discuss the geometric effects of some symmetries on such manifolds and show, under a certain condition, that the class of Ricci semi-symmetric nearly Sasakian manifolds is a subclass of

Applications of Disaffinity Vectors to Certain Riemannian Manifolds

Mathematics
A disaffinity vector on a Riemannian manifold is a vector field whose affinity tensor vanishes. In this paper, we prove that every disaffinity vector on a compact Riemannian manifold is an incompressible vector field.
