## Note on Lie derivatives and divergences

When can you integrate-by-parts with Lie derivatives?

## Note on generating a divergence identity

Special thanks to Ben Mares for coming up with this identity.

## Note on a (dimension-dependent) Weyl identity

There is a nice 4-dimensional Weyl identity that I can never seem to remember off the top of my head; so I decided I need to write this note so I don’t have ...

## Notes on the Weyl, E/B, and 3+1 decompositions of Riemann, and curvature invariants

The Weyl decomposition, further splitting into E/B, and computing in terms of 3+1 objects
