ProofWiki:Potw

Current Proof of The Week  Complex Numbers cannot be Totally Ordered

HOW TO USE THIS PAGE

 * 1. Select the proof P you want to put up as POTW.
 * 2. Edit P to put this at the top:




 * replacing   with today's date.


 * 3. Edit the previous POTW to change:
 * to:
 * to:


 * 4. Edit this page to:
 * (a) add the old POTW to the top of the list;
 * (b) put the new POTW into the two places where the last one was.


 * 5. There appears to be a bug in MediaWiki (at least, in the version installed as of the 4th July 2014) which causes any transcluded pages not to be refreshed in a parent page until that parent page is edited.


 * So, the final step is: Edit and Save the Main Page (making no changes to it).
