Birkhoff's Theorem for Quasi-Metric Gravity

General Relativity and Quantum Cosmology 2024-04-02 v3

Abstract

Working within the quasi-metric framework (QMF), it is examined if the gravitational field exterior to an isolated, spherically symmetric body is necessarily metrically static, or equivalently, whether or not Birkhoff's theorem holds for quasi-metric gravity. It is found that it does; however the proof is somewhat different from the general-relativistic case.
