二阶规范不变宇宙学扰动理论中单标量场方程的相容性

Consistency of Equations for the Single Scalar Field Case in Second-order Gauge-invariant Cosmological Perturbation Theory

Kouji Nakamura

摘要:

我们推导了爱因斯坦方程和Klein-Gordon方程的规范不变变量的一般情况下的二阶微扰。证明了所有方程的一致性。这一确认意味着所有导出的二阶方程是自洽的,并且这些方程在这个意义上是正确的。我们还讨论了这些方程的物理含义。

英文摘要:

We derived the second-order perturbations of the Einstein equations and the Klein-Gordon equation for a generic situation in terms of gauge-invariant variables. The consistency of all the equations is confirmed. This confirmation implies that all the derived equations of the second order are self-consistent and these equations are correct in this sense. We also discuss the physical implication of these equations.
