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

Journal 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
Journal 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.

A New Class of Contact Pseudo Framed Manifolds with Applications
International 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
Journal 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.

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.
