Definition:Big-Omega Notation/Notation

Notation for $\Omega$ Notation

The expression $\map f n \in \map \Omega {\map g n}$ is read as:

$\map f n$ is big-omega of $\map g n$

While it is correct and accurate to write:

$\map f n \in \map \Omega {\map g n}$

it is a common abuse of notation to write:

$\map f n = \map \Omega {\map g n}$

This notation offers some advantages.
