Assume a torsionless space-time. Is there any name for this tensor, provided it exists?
[tex] G_{\alpha\beta} =\nabla_{\mu}\nabla_{\nu} T^{\mu\alpha|\nu\beta} [/tex]
,where G is of course the Einstein tensor...?
My comment would be that it doesn't exist, since the algebra of the covariant derivatives implies that T=0.
