Definition:Ordinal Space/Closed/Uncountable

Definition
Let $\Omega$ denote the first uncountable ordinal.

The uncountable closed ordinal space on $\Omega$ is the particular case of a closed ordinal space $\left[{0 \,.\,.\, \Gamma}\right]$ where $\Gamma = \Omega$.

That is, it is the set $\left[{0 \,.\,.\, \Omega}\right]$ of all ordinal numbers less than or equal to $\Omega$, together with the order topology.
