Gauge and Hyperbolicity in General Relativity<br />
The spacetime Ricci curvature tensor can be written as:<br />
R ab = − 1 2 ψcd ∂ c ∂ d ψ ab + ∇ (a Γ b) + Q ab (ψ, ∂ψ),<br />
where ψ ab is the 4-metric, and Γ a = ψ ad ψ bc Γ d bc .<br />
Like Maxwell’s equations, these equations can not be solved<br />
without specifying suitable gauge conditions.<br />
