Conformal Killing Forms on Totally Umbilical Submanifolds

Journal of Mathematical Sciences, 2016
For a \(C^{\infty}\)-manifold \(M\) with a pseudo-Riemannian metric \(g\) and Levi-Civita connection \(\nabla\), an \(r\)-form \(\omega\) on \(M\) is called a conformal Killing form if it satisfies the differential equation: \[ \nabla\omega-\frac{1}{r+1}d\omega+g\wedge\theta=0 \] for some \((r-1)\)-form \(\theta\).

Killing tensors from conformal Killing vectors

Classical and Quantum Gravity, 1992
Killing vectors are usual known or at least not very hard to find. Conformal Killing vectors are much harder to find and consequently the process of finding the corresponding Killing tensors of order 2 is more difficult. The aim of this paper is to explicitly obtain Killing tensors of order 2 without solving the classical equations.

Special Killing forms on Lorentzian spin manifolds

2011 International Conference on Computer Science and Service System (CSSS), 2011
The aim of this paper is to give some conformal Killing forms, some Killing and special Killing forms concerning the geometry of Lorentzian spin manifolds admitting imaginary Killing spinors. By the Dirac current flow V ϕ of an imaginary killing spinor ϕ.

The Killing form for graded Lie algebras

Journal of Mathematical Physics, 1977
A Killing form with nice symmetry and invariance properties is constructed for an arbitrary graded Lie algebra. When this form is nondegenerate, Casimir operators can be constructed, and the graded Lie algebra possesses properties analogous to those possessed by semisimple ordinary Lie algebras.
