<br />
The separation axioms along with other properties form a network of implications:<br />
<br />

<br />
It's interesting to note that paracompactness (every open cover has a subcover such that every point has a neighbourhood that intersects finitely many elements) will suffice in place of compactness.</div>Colahhttp://drorbn.net/index.php?title=10-327/Compactness10-327/Compactness2010-12-19T20:53:10Z<p>Colah: </p>

While we only discussed normal compactness, there are a lot of variations. I thought this graph of the implications between the different properties might be of interest.<br />
