  This is the wiki for ''polymath'' projects  massively collaborative online mathematical projects. The idea of such projects originated in Tim Gowers' blog post [http://gowers.wordpress.com/2009/01/27/ismassivelycollaborativemathematicspossible/ Is massively collaborative mathematics possible?]
 +  
   +  
  Many polymath projects will be proposed, planned, and run at [http://polymathprojects.org/ This Blog].
 +  
   +  
  A Polymath [[logo]] is being trialled. If you have more suggestions, please add them to the [[logo]] page, or add to the discussion at [[Talk:logo]].
 +  
   +  
  == Existing polymath projects ==
 +

  A (partial) list of proposed projects can be found [http://polymathprojects.org/category/polymathproposals/ here].
 +  
   +  
  If you have a tentative proposal for a polymath project, you can either make a post on it on your own blog, or place it [[other proposed projectshere]].
