f(R)-引力牛顿极限的一般解

A general solution in the Newtonian limit of f(R)- gravity

S. Capozziello, A. Stabile, A. Troisi

摘要:

我们表明,任何解析$f(R)$重力模型,在度量方法,提出了一个弱场限制的标准牛顿势是由Yukawa的长期校正。这个一般性结果从未被指出过,但对于某些特殊的理论却经常得到。这意味着只有$f(R)=R$允许恢复标准牛顿势,而这不是其他相对论引力理论的情况。这样一个一般的解决方案的物理后果的一些考虑得到解决。

英文摘要:

We show that any analytic $f(R)$-gravity model, in the metric approach, presents a weak field limit where the standard Newtonian potential is corrected by a Yukawa-like term. This general result has never been pointed out but often derived for some particular theories. This means that only $f(R)=R$ allows to recover the standard Newton potential while this is not the case for other relativistic theories of gravity. Some considerations on the physical consequences of such a general solution are addressed.
