Komar superpotential
text:
In general relativity, the Komar superpotential, corresponding to the invariance of the Hilbert–Einstein Lagrangian L G = 1 2 κ R − g d 4 x , is the tensor density: associated with a vector field ξ = ξ ρ ∂ ρ , and where ∇ σ denotes covariant derivative with respect to the Levi-Civita connection. The Komar two-form: where d x α β = ι ∂ α d x β = ι ∂ α ι ∂ β d 4 x denotes interior product, generalizes to an arbitrary vector field ξ the so-called above Komar superpotential, which was originally der
