......@@ -35,7 +35,7 @@ respectively. Following \cite{Peebles1980} (ch.7), we introduce the
gauge transformation $\Lag \rightarrow \Lag + \frac{d}{dt}\Psi$ with
$\Psi \equiv \frac{1}{2}a\dot{a}\mathbf{r}_i^2$ and obtain
\begin{align}
\Lag &= \frac{1}{2}m_ia^2 \dot{\mathbf{r}}_i^2 -
\Lag &= \frac{1}{2}m_ia^2 \dot{\mathbf{r}}_i'^2 -
