替代引力中的Jebsen-Birkhoff定理

The Jebsen-Birkhoff theorem in alternative gravity

Valerio Faraoni

摘要:

我们讨论的有效性,或缺乏,在标量张量理论的Jebsen-Birkhoff定理的推广,并把Brans-Dicke标量作为有效的物质。讨论了Jordan和Einstein框架,澄清了标量-张量引力的静态球解与Brans-Dicke黑洞的Hawking定理之间的一个明显矛盾.结果适用于度量和Palatini f(R)引力。

英文摘要:

We discuss the validity, or lack thereof, of the Jebsen-Birkhoff theorem in scalar-tensor theories by generalizing it and regarding the Brans-Dicke-like scalar as effective matter. Both the Jordan and Einstein frames are discussed and an apparent contradiction between static spherical solutions of scalar-tensor gravity and Hawking's theorem on Brans-Dicke black holes is clarified. The results are applied to metric and Palatini f(R) gravity.
