This is the wiki for polymath projects - massively collaborative online mathematical projects. The idea of such projects originated in Tim Gowers' blog post Is massively collaborative mathematics possible?

Many polymath projects will be proposed, planned, and run at this blog.

Existing polymath projects

Polymath1: New proofs and bounds for the density Hales-Jewett theorem. Initiated Feb 1, 2009; now in the process of writing up the results.
Polymath2: Must an “explicitly defined” Banach space contain c_0 or ell_p? Initiated Feb 17, 2009; largely inactive at present
Mini-polymath1: Solving Problem 6 of the 2009 International Mathematical Olympiad. Initiated July 20, 2009; five proofs obtained so far.
Polymath3. The polynomial Hirsch conjecture. Proposed July 17, 2009.
Polymath4: A deterministic way to find primes. Proposed July 27, 2009; launched Aug 9, 2009. Somewhat inactive at present.
Polymath5. The Erdős discrepancy problem. Proposed Jan 10, 2010; launched Jan 19, 2010.

Proposed polymath projects

The cap set problem. Proposed March 25, 2009 (see also these two followup posts).
Boshernitzan’s problem. Proposed July 27, 2009.
Possible future polymath projects. Discussion opened September 16, 2009.

A (partial) list of proposed projects can be found 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 here.
