2-Conformal Vector Fields on the Model Sol Space and Hyperbolic Ricci Solitons
Journal of MathematicsIn this study, we present the notion of 2-conformal vector fields on Riemannian and semi-Riemannian manifolds, which are an extension of Killing and conformal vector fields. Next, we provide suitable vector fields in Sol space that are 2-conformal. A few

On an Anti-Torqued Vector Field on Riemannian Manifolds
Mathematics, 2021 A torqued vector field ξ is a torse-forming vector field on a Riemannian manifold that is orthogonal to the dual vector field of the 1-form in the definition of torse-forming vector field. In this paper, we introduce an anti-torqued vector field which is

On Generalized Recurrent and Generalized Concircularly Recurrent Weyl Manifolds
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021 In the present work, generalized recurrent and generalized concircularly recurrent Weyl manifolds are examined. We define nearly quasi-Einstein Weyl manifolds and we proved that if a generalized recurrent or generalized concircularly recurrent Weyl ...

Conformal η-Ricci Solitons on Riemannian Submersions under Canonical Variation
Axioms, 2022 This research article endeavors to discuss the attributes of Riemannian submersions under the canonical variation in terms of the conformal η-Ricci soliton and gradient conformal η-Ricci soliton with a potential vector field ζ.

Concircular vector fields and pseudo-Kaehler manifolds [PDF]
Kragujevac Journal of Mathematics, 2016 A vector field on a pseudo-Riemannian manifold N is called concircular if it satisfies ΔXv = μX for any vector X tangent to N, where ∆ is the Levi-Civita connection of N. A concircular vector field satisfying ∆Xv = µX is called a nontrivial concircular vector field if the function µ is non-constant.

Energy–Momentum Squared Gravity Attached with Perfect Fluid Admitting Conformal Ricci Solitons
UniverseIn the present research note, we explore the nature of the conformal Ricci solitons on the energy–momentum squared gravity model F(R,T2) that is a modification of general relativity.

Anti-Invariant Lorentzian Submersions From Lorentzian Concircular Structure Manifolds
Frontiers in Physics, 2022 This research article attempts to investigate anti-invariant Lorentzian submersions and the Lagrangian Lorentzian submersions (LLS) from the Lorentzian concircular structure [in short (LCS)n] manifolds onto semi-Riemannian manifolds with relevant non ...

Characterizing small spheres in a unit sphere by Fischer–Marsden equation
Journal of Inequalities and Applications, 2022 We use a nontrivial concircular vector field u on the unit sphere S n + 1 $\mathbf{S}^{n+1}$ in studying geometry of its hypersurfaces. An orientable hypersurface M of the unit sphere S n + 1 $\mathbf{S}^{n+1}$ naturally inherits a vector field v and a ...

On harmonic and biharmonic maps from gradient Ricci solitons
Mathematische Nachrichten, Volume 296, Issue 11, Page 5109-5122, November 2023., 2023 Abstract We study harmonic and biharmonic maps from gradient Ricci solitons. We derive a number of analytic and geometric conditions under which harmonic maps are constant and which force biharmonic maps to be harmonic. In particular, we show that biharmonic maps of finite energy from the two‐dimensional cigar soliton must be harmonic.
