共形框架与Birkhoff定理的有效性
Conformal frames and the validity of Birkhoff's theorem
摘要：
伯克霍夫定理是爱因斯坦广义相对论最重要的陈述之一，一般不能推广到修正的引力理论。在这里，我们研究的有效性定理的标量张量理论使用微扰的方法，并比较结果在所谓的爱因斯坦和约旦框架。结果的影响问题的物理等价性，至少在扰动两个框架。
英文摘要：
Birkhoff's theorem is one of the most important statements of Einstein's general relativity, which generally can not be extended to modified theories of gravity. Here we study the validity of the theorem in scalar-tensor theories using a perturbative approach, and compare the results in the so-called Einstein and Jordan frames. The implications of the results question the physical equivalence between both frames, at least in perturbations.
