# FLRW curvature

14 Feb 2018whatâ€™s the invariant curvature \(R^{abcd}R_{abcd}\) of the FLRW metric? which information is not contained in the Ricci scalar \(R=g^{ac}g^{bd}R_{abcd}\)? would one expect anything non-local (i.e. not contained in the Ricci-scalar) at all for homogeneous matter distribution?
