A Study on Ricci Solitons in Kenmotsu Manifolds

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
We study and obtain results on Ricci solitons in Kenmotsu manifolds satisfying R(ξ, X) · B = 0, B(ξ, X) · S = 0, S(ξ, X) · R = 0, R(ξ,X)·P¯=0, and P¯(ξ,X)·S=0, where B and P¯ are C‐Bochner and pseudo‐projective curvature tensor.

Certain Results on Ricci Solitons in α‐Sasakian Manifolds

Geometry, Volume 2013, Issue 1, 2013., 2013
We study Ricci solitons in α‐Sasakian manifolds and show that it is a shrinking or expanding soliton and the manifold is Einstein with Killing vector field. Further, we prove that if V is conformal Killilng vector field, then the Ricci soliton in 3‐dimensional α‐Sasakian manifolds is shrinking or expanding but cannot be steady.

Certain Results on Ricci Solitons in Trans‐Sasakian Manifolds

Journal of Mathematics, Volume 2013, Issue 1, 2013., 2013
We study and obtain results on Ricci solitons in trans‐Sasakian manifolds satisfying R(ξ,X)·C̃=0, P(ξ,X)·C̃=0, H(ξ, X) · S = 0, and C̃(ξ,X)·S=0, where C̃, P, and H are quasiconformal, projective, and conharmonic curvature tensors.

Ricci Solitons in α‐Sasakian Manifolds

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
We study Ricci solitons in α‐Sasakian manifolds. It is shown that a symmetric parallel second order‐covariant tensor in a α‐Sasakian manifold is a constant multiple of the metric tensor. Using this, it is shown that if ℒVg + 2S is parallel where V is a given vector field, then (g, V, λ) is Ricci soliton.

Some Solitons on Lorentzian Para-Kenmotsu Manifolds

Sarajevo Journal of Mathematics
In this paper we study the nature of the Einstein soliton and $\eta $-Einstein soliton in the framework of Lorentzian para-Kenmotsu manifolds (briefly, LP-Kenmotsu manifolds). We find an expression for scalar curvature of LP-Kenmotsu manifolds admitting the Einstein soliton and $\eta $-Einstein soliton in various cases.

On Curvatures of Semi-invariant Submanifolds of Lorentzian Para-Sasakian Manifolds

, 2023
A Lorentzian para-Sasakian (LP-Sasakian) space form is a kind of para-Sasakian manifold with constant φ− holomorphic sectional curvature. The presented paper is on the curvatures of semi-invariant submanifolds of an LP-Sasakian space form.

Harmonic (p, q)‐Curves in Trans‐Sasakian and Normal Almost Paracontact Metric Manifolds

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we give some characterizations about biharmonic, f‐harmonic, and f‐biharmonic (p, q)‐curves in 3‐dimensional trans‐Sasakian and normal almost paracontact metric manifolds. The (p, q)‐curves are considered as generalizations of magnetic curves.
