ρ‐Einstein Solitons on Warped Product Manifolds and Applications

open access: yesJournal of Mathematics, Volume 2022, Issue 1, 2022., 2022
The purpose of this research is to investigate how a ρ‐Einstein soliton structure on a warped product manifold affects its base and fiber factor manifolds. Firstly, the pertinent properties of ρ‐Einstein solitons are provided. Secondly, numerous necessary and sufficient conditions of a ρ‐Einstein soliton warped product manifold to make its factor ρ ...

Conformal η‐Ricci‐Yamabe Solitons within the Framework of ϵ‐LP‐Sasakian 3‐Manifolds

open access: yesAdvances in Mathematical Physics, Volume 2022, Issue 1, 2022., 2022
In the present note, we study ϵ‐LP‐Sasakian 3‐manifolds M3(ϵ) whose metrics are conformal η‐Ricci‐Yamabe solitons (in short, CERYS), and it is proven that if an M3(ϵ) with a constant scalar curvature admits a CERYS, then £Uζ is orthogonal to ζ if and only if Λ − ϵσ = −2ϵl + (mr/2) + (1/2)(p + (2/3)). Further, we study gradient CERYS in M3(ϵ) and proved

Biharmonic Curves in a Strict Walker 3‐Manifold

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2022, Issue 1, 2022., 2022
In this paper, we study the geometry of biharmonic curves in a strict Walker 3‐manifold and we obtain explicit parametric equations for biharmonic curves and time‐like biharmonic curves, respectively. We discuss the conditions for a speed curve to be a slant helix in a Walker manifold.

Sub‐Lorentzian Geometry of Curves and Surfaces in a Lorentzian Lie Group

open access: yesAdvances in Mathematical Physics, Volume 2022, Issue 1, 2022., 2022
We consider the sub‐Lorentzian geometry of curves and surfaces in the Lie group E(1, 1). Firstly, as an application of Riemannian approximants scheme, we give the definition of Lorentzian approximants scheme for E(1, 1) which is a sequence of Lorentzian manifolds denoted by Eλ1,λ2L.

The Sub‐Riemannian Limit of Curvatures for Curves and Surfaces and a Gauss‐Bonnet Theorem in the Group of Rigid Motions of Minkowski Plane with General Left‐Invariant Metric

open access: yesJournal of Function Spaces, Volume 2021, Issue 1, 2021., 2021
The group of rigid motions of the Minkowski plane with a general left‐invariant metric is denoted by (E(1, 1), g(λ1, λ2)), where λ1 ≥ λ2 > 0. It provides a natural 2‐parametric deformation family of the Riemannian homogeneous manifold Sol3 = (E(1, 1), g(1, 1)) which is the model space to solve geometry in the eight model geometries of Thurston. In this

A Note on LP‐Sasakian Manifolds with Almost Quasi‐Yamabe Solitons

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
We categorize almost quasi‐Yamabe solitons on LP‐Sasakian manifolds and their CR‐submanifolds whose potential vector field is torse‐forming, admitting a generalized symmetric metric connection of type (α, β). Finally, a nontrivial example is provided to confirm some of our results.

Geodesic Lightlike Submanifolds of Lorentzian Para-Sasakian Manifolds

open access: yesJournal of Physics: Conference Series, 2022
Abstract In this paper we study invariant lightlike submanifolds of Lorentzian para-sasakian manifolds. We investigate geodesic CR-lightlike submanifolds of Lorentzian para-sasakian manifolds. We study screen CR-lightlike submanifolds of Lorentzian para-sasakian manifolds.

A New Class of Contact Pseudo Framed Manifolds with Applications

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2021, Issue 1, 2021., 2021
In this paper, we introduce a new class of contact pseudo framed (CPF)‐manifolds (M, g, f, λ, ξ) by a real tensor field f of type (1,1), a real function λ such that f3 = λ2f where ξ is its characteristic vector field. We prove in our main Theorem 2 that M admits a closed 2‐form Ω if λ is constant.

Pseudo‐Parallel Characteristic Jacobi Operators on Contact Metric 3 Manifolds

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
We prove that the characteristic Jacobi operator on a contact metric three manifold is semiparallel if and only if it vanishes. We determine Lie groups of dimension three admitting left invariant contact metric structures such that the characteristic Jacobi operators are pseudoparallel.
