     Let $G \curvearrowright X$ be a $G$-flow and $x \in X$, then the following are equivalent:
     \begin{enumerate}
         \item For each $U \in \cn_X(x)$, $N(x, U)$ is infinite. 
-        \item There exists $\fU \in \beta G \setminus G$ such that $px = x$. 
+        \item There exists $\fU \in \beta G \setminus G$ such that $\fU x = x$.
