In my calculations, I come across the scalar
[tex]R^{ji} R_{ij} - R^2[/tex]
([tex]R_{ij}[/tex] is the Ricci tensor, [tex]R[/tex] is the Ricci scalar)
More specifically, I come across the integral of this scalar over a compact manifold.
Has anyone seen it before, and does it have any nice properties?
