On m-Modified Conformal Vector Fields

The Journal of Geometric Analysis, 2023
The 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, 2001
Summary: 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, 1999
The 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, 2023
The 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 ...
