Definition:Limit Inferior of Sequence of Sets/Notation

Definition
Let $\left\{{E_n : n \in \N}\right\}$ be a sequence of sets.

The limit inferior of $E_n$ can also be seen denoted as:
 * $\displaystyle \underline {\lim}_{n \to \infty} \ E_n$

but this notation is not used on because it does not render well.
