\def \varAsym {{\color{royalblue} g(n)}}

\omega(\varAsym)
$$
In linguaggio formale, $\varFunc$ è in $\omega(\varAsym)$ se:
$$
\omega(\varAsym)
\Longleftrightarrow
\begin{cases}
\forall & \varLess > 0\\
\\
: & \begin{cases}
\exists & \varBeginning > 0\\
\forall & n \geq \varBeginning\\
: & 0 \leq (\varLess \cdot \varAsym) \leq \varFunc
\end{cases}
\end{cases}
$$
