Geometry of Harmonic Nearly Trans-Sasakian Manifolds

open access: yesAxioms, 2023
This paper considers a class of nearly trans-Sasakian manifolds. The local structure of nearly trans-Sasakian structures with a closed contact form and a closed Lee form is obtained. It is proved that the class of nearly trans-Sasakian manifolds with a closed contact form and a closed Lee form coincides with the class of almost contact metric manifolds

$\eta$-Ricci solitons in $(\varepsilon)$-almost paracontact metric manifolds

open access: yes, 2017
The object of this paper is to study $\eta$-Ricci solitons on $(\varepsilon)$-almost paracontact metric manifolds. We investigate $\eta$-Ricci solitons in the case when its potential vector field is exactly the characteristic vector field $\xi$ of the $(\

Nearly trans-Sasakian almost 𝐶(𝜆)-manifolds

open access: yesChebyshevskii Sbornik
The nearly trans-Sasakian manifolds, which are almost 𝐶(𝜆)-manifolds, are considered. On the space of the adjoint G-structure, the components of the Riemannian curvature tensor, the Ricci tensor of the nearly trans-Sasakian manifolds, and the almost 𝐶(𝜆)-manifolds are obtained.Identities are obtained that are satisfied by the Ricci tensor of nearly ...
