On m-Modified Conformal Vector Fields
The Journal of Geometric Analysis, 2023The authors introduce the notion of \(m\)-modified conformal vector fields. It is shown that compact Riemannian manifolds admit no \(m\)-modified conformal vector fields of constant length. It is also shown that the existence of a left-invariant \(m\)-modified conformal vector field on a Riemannian Lie group \(\left( G,\left\langle \cdot ,\cdot \right ...

On $\phi$-skew symmetric conformal vector fields
Publicationes Mathematicae Debrecen, 2001Summary: The notion of the \(J\)-skew symmetric vector field was introduced by \textit{I. Mihai, L. Nicolescu} and \textit{R. Rosca} [Port. Math. 54, 215-228 (1997; Zbl 0880.53029)]. In the present paper, we deal with \(\varphi\)-skew symmetric conformal vector fields on a Kenmotsu manifold \(M(\varphi,\Omega,\eta,\xi,g)\).

Essential conformal vector fields
Classical and Quantum Gravity, 1999The author deduces the necessary and sufficient condition for a conformal Killing vector field on a pseudo-Riemannian manifold \((M,g)\) to be homothetic or even a Killing vector field with respect to a locally defined metric conformally related to \(g\).

Conformal Vector Fields on Finsler Warped Product Manifolds
Acta Mathematica Sinica, English Series, 2023The authors study Finsler manifolds which are equipped with a special form of Finsler metric known as Finsler warped product metric, and investigate conformal vector fields on such manifolds. They obtain a system of equivalent equations in Theorem 1.1 that the conformal vector fields on Finsler warped product manifolds satisfy and which completely ...

Conformal Vector Fields and Conformal–Type Collineations in Space-Times
General Relativity and Gravitation, 2000This article discusses the existence of homothetic and conformal vector fields in spacetimes with a Killing symmetry. The study of Weyl invariants along the integral curves of the conformal vector fields leads to restrictions for the existence of such fields. A non-existence theorem for proper conformal fields in spacetimes of certain Petrov classes is

Conformal vector fields on Finsler manifolds
International Journal of Mathematics, 2020In this paper, we give an equivalent characterization of conformal vector fields on a Finsler manifold [Formula: see text], whose metric [Formula: see text] is defined by a Riemannian metric [Formula: see text] and a 1-form [Formula: see text]. This characterization contains all related results in [Z. Shen and Q.
