Please identify yourself in this photo! There are two ways to do that:&lt;br /&gt;
&lt;br /&gt;
* [[Special:Userlogin|Log in]] to this Wiki and edit this page. Put your name, userid, email address and location in the picture in the alphabetical list below.&lt;br /&gt;

Since I made a mistake with the pathes and these files will likely be deleted or moved, I&#039;m including a link to the [http://christopherolah.wordpress.com/2010/08/14/separation-axiom-visualisations/ original source on my blog].&lt;br /&gt;
&lt;br /&gt;
The separation axioms along with other properties form a network of implications:&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
It&#039;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.&lt;/div&gt;</summary>

&lt;br /&gt;
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.&lt;br /&gt;
