曲率摄动的共形不变性

Conformal invariance of curvature perturbation

Jinn-Ouk Gong, Jai-chan Hwang, Wan Il Park, Misao Sasaki, Yong-Seon Song

摘要:

我们证明了在单分量情形下,共动规范中的所有微扰变量对所有微扰阶都是共形不变的。一般来说,我们确定一个特殊的时间切片,均匀共形变换切片,所有的扰动再次共形不变的所有扰动订单。我们将这个结果应用到Δ N形式主义,并显示其共形不变性。

英文摘要:

We show that in the single component situation all perturbation variables in the comoving gauge are conformally invariant to all perturbation orders. Generally we identify a special time slicing, the uniform-conformal transformation slicing, where all perturbations are again conformally invariant to all perturbation orders. We apply this result to the delta N formalism, and show its conformal invariance.
