Conformal Vector Fields and Null Hypersurfaces

Results in Mathematics, 2022
Abstract We give conditions for a conformal vector field to be tangent to a null hypersurface. We particularize to two important cases: a Killing vector field and a closed and conformal vector field. In the first case, we obtain a result ensuring that a null hypersurface is a Killing horizon.

On the coupling of vector fields to the Gauss-Bonnet invariant

Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales, 2021
Inflationary models including vector fields have attracted a great deal of attention over the past decade. Such an interest owes to the fact that they might contribute to, or even be fully responsible for, the curvature perturbation imprinted in the ...

General light-cone gauge approach to conformal fields and applications to scalar and vector fields [PDF]

, 2022
Totally symmetric arbitrary spin conformal fields propagating in the flat space of even dimension greater than or equal to four are studied. For such fields, we develop a general ordinary-derivative light-cone gauge formalism and obtain restrictions ...

A classification of conformal vector fields on the tangent bundle

Ukrains’kyi Matematychnyi Zhurnal, 2020
UDC 514.7 Let ( M , g ) be a Riemannian manifold and T M be its tangent bundle equipped with a Riemannian (or pseudo-Riemannian) lift metric derived from g .  We give a classification of infinitesimal fibre-preserving conformal transformations on the tangent bundle.

Pseudo-Riemannian Lie groups admitting left-invariant conformal vector fields

Comptes Rendus. Mathématique, 2020
Let $G$ be a Lorentzian Lie group or a pseudo-Riemannian Lie group of type $(n-2,2)$. If $G$ admits a non-Killing left-invariant conformal vector field, then $G$ is solvable.
