Every Lie group $G$ has the following escape property: For every $x \ne e$ in a sufficiently small neighborhood $U$ of the identity $e$ in $G$, there is a integer $n$ such that $x^n$ is not in $U$.
The question is if we can find a sufficiently small neighborhood $V$ of $e$ in $G$, for any two different points $a,b \in V$ , there is a integer $m$ such that $a^m(b^{-1})^m$ is not in $V$.
If G is Commutative group, the question actually is true, since G has escape property. I guess it is true for some class except Commutative group. The problem is to state that Power mapping can enlarge the distance between two different points. But,I didn't find a good property of power mapping by looking up data. meanwhile,Thanks Michael Albanese for editing of question.
