In weak gravitaional fields, we can write equations analogous to the Maxwell equations: Gravitoelectromagnetism.
- Do the gravitoelectric field and the gravitomagnetic field transform like components of a second rank tensor (2-form, to be exact) analogous to the Faraday tensor?
If so,
Does this tensor have some immediate relation to the Riemann/Ricci/Einstein tensors?
Can we use it to write the Einstein-Hilbert action in Yang-Mills form in this approximation?
