The Post-Newtonian Approximation in Massive Gravity
We briefly review the post-Newtonian expansion as a way to yield the approximate equations of motion from a metric theory of gravity in the slow-motion, weak-field limit. Then,the parameterized post-Newtonian (PPN) formalism is introduced, as it provides a method of characterizing metric theories of...

Sumario: | We briefly review the post-Newtonian expansion as a way to yield the approximate equations of motion from a metric theory of gravity in the slow-motion, weak-field limit. Then,the parameterized post-Newtonian (PPN) formalism is introduced, as it provides a method of characterizing metric theories of gravity (again, in the slow-motion, weak-field limit). Finally,the field equations for Lorentz-violating massive gravity are derived from the Lagrangian; these equations will allow for the future determination of the PPN parameters. |
