This category contains examples of Open Set (Complex Analysis).
Let $S \subseteq \C$ be a subset of the set of complex numbers.
Let:
- $\forall z_0 \in S: \exists \epsilon \in \R_{>0}: N_{\epsilon} \left({z_0}\right) \subseteq S$
where $N_{\epsilon} \left({z_0}\right)$ is the $\epsilon$-neighborhood of $z_0$ for $\epsilon$.
Then $S$ is an open set (of $\C$), or open (in $\C$).
