论文摘要
在此简短说明中,我们提出了一个微不足道的结果。也就是说,我们表明扰动脱壳$ f(r)$ - 理论等于爱因斯坦的重力,以及布兰斯·迪克理论和爱因斯坦标量的田地模型。我们还讨论了该结果对高阶重力场模型的可能概括。
In this brief note we present a somewhat trivial result. Namely, we show that perturbative off-shell $f(R)$-theory is equivalent to Einstein gravity, as well as to the Brans-Dicke theory and the Einstein scalar field model. We also discuss possible generalisation of this result to higher-order gravitational field models.
