== Polymath-like projects ==


A spreadsheet containing the latest upper and lower bounds for <math>c_n</math> can be found [http://spreadsheets.google.com/ccc?key=p5T0SktZY9DsU-uZ1tK7VEg here]. Here are the proofs of our [[upper and lower bounds]] for these constants.

* A wiki page clearinghouse for the [[Deolalikar P vs NP paper]].  Launched Aug 10, 2010.
* <del>[http://researchtrends.wikia.com/wiki/Main_Page Math Research Trends Wiki] "research in the middle"</del> This project is recommended to be discontinued in favor of <b>[https://conference.portonvictor.org/wiki/Research_in_the_middle Research in the middle project] at [https://conference.portonvictor.org Virtual scientific conference]</b>.
* The page for the [[ABC conjecture]] contains links and information about Mochizuki's claimed proof of this conjecture.
* A [[COVID-19 dataset clearinghouse]].
* Massively Collaborative Theoretical Computer Science Projects at [https://polytcs.wordpress.com/ The PolyTCS Project], by Rupei Xu and Chloe Yang.


We are also collecting bounds for [[Fujimura's problem]], motivated by a [[hyper-optimistic conjecture]].
== Proposed polymath projects ==


There is also a chance that we will be able to improve the known bounds on [[Moser's cube problem]].
* [http://gilkalai.wordpress.com/2009/03/25/an-open-discussion-and-polls-around-roths-theorem/ The cap set problem].  Proposed March 25, 2009 (see also these [http://gilkalai.wordpress.com/2009/05/11/around-the-cap-set-problem-b/ two] [http://gilkalai.wordpress.com/2009/05/18/the-cap-set-problem-and-frankl-rodl-theorem-c/ followup] posts).
* [[Boshernitzan’s problem]].  Proposed July 27, 2009.
* [http://gowers.wordpress.com/2009/09/16/possible-future-polymath-projects/ Possible future polymath projects].  Discussion opened September 16, 2009.
* [http://rjlipton.wordpress.com/2011/05/12/a-possible-polymath-project/ A possible polymath project:] Proposal by Richard Lipton to attack a conjecture due to Erdos, about a class of Diophantine equations.


Here are some [[unsolved problems]] arising from the above threads.


Here is a [[tidy problem page]].
A (partial) list of proposed projects can be found [http://polymathprojects.org/category/polymath-proposals/ here].


== Proof strategies ==
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 projects|here]].


It is natural to look for strategies based on one of the following:

All these theorems are worth knowing. The most immediately relevant are Roth's theorem, Sperner's theorem, Szemer&eacute;di's regularity lemma and the triangle removal lemma, but some of the others could well come into play as well.

Latest revision as of 12:25, 1 September 2020

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.

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.

The wiki is currently locked down due to a major influx of spam (July 29, 2013). Please email thomas@asone.ai if you'd like an account set up, and I'll do my best to reply quickly.
