Aug 10, 2016 at 20:51 comment added Gil Kalai Dear Yiftach, I dont know enough about the proof and the problem to even tell. I suspect it wont be a good polymath project. This said, one should mention the glorious question and answers here on MO mathoverflow.net/questions/106560/… which was some kind of collective effort (by a few courageous individuals) to understand Mochizuki's approach.

Aug 10, 2016 at 9:21 comment added Yiftach Barnea This is not my research area and my understanding of it is zero. However, I was wondering if trying to understand Mochizuki's proof of the ABC conjecture wouldn't be a good polymath project. It seems that people are struggling to do that on their own, but it looks like a topic where knowledge can be accumulated and shared. So for instance, if someone constructs some example, it could help other people. Also, of course discussions between people can also help here a lot.

Jan 29, 2016 at 1:29 comment added Asaf Karagila Since I'm entirely unfamiliar with polymath projects, I was just idly wondering if progress which is non-effective is considered progress. Namely proving existence without giving any bounds or means for finding examples... (Particularly for the number theoretic or combinatorial problems)

Oct 2, 2015 at 4:59 comment added Gil Kalai One more remark regarding the level of problems. In four out of the five first polymath projects the problems were well known and central open problems in their field (while not among the famous problems of mathematics). Polymath2 was a more open-ended project but it also reflected a question that experts in the relevant field were thinking about for decades.

Oct 1, 2015 at 14:46 comment added Gil Kalai Joel, John and all. I did find a very relevant link about the criteria for choosing the very first polymath project: gowers.wordpress.com/2009/02/01/why-this-particular-problem I think that they are very good (of course, with more projects different criteria can be experimented.)

Oct 1, 2015 at 6:20 comment added Gil Kalai John, There could be divide and conquer aspect also when different people work on different avenues of attack on the conjecture which can split and merge during the project. (So this allows in theory sharply different "global view" on the problem.) So far, I think that most participants worked what was considered the most promising avenue. (With competing ideas how to proceed "locally"). Maybe Tim and Terry can say more about experiences from earlier polymath projects. (And perhaps also from the micro projects.)
Oct 1, 2015 at 5:42 comment added Gil Kalai Dear Joel, I thing some criteria were proposed (what I meant that we do not know what makes a good polymath project). It is probably good to have that the problem/task itself will have general appeal. I will try to find links to relevant discussions. Dear John, most polymath projects so far did not have a clear divide and conquer nature. The experience so far is that the emerging set of main contributors was not large (5-15, or less, I would say, with a larger group of observers and occasional contribitors) and they all had some global view on the problem.
Oct 1, 2015 at 5:20 comment added John C. Baez I imagine that a good polymath problem would be one where it's reasonable to take a "divide and conquer" approach, breaking things down into cases, and sending in the troops to tackle different cases. Otherwise the only people who can contribute a lot are those with a global view of the problem, and that means that in the end just a few will contribute.

Sep 30, 2015 at 21:19 comment added Gil Kalai Dear Joel, I do not think we know the answer to your question. In fact, this is part of what is explored. But there were discussions about it in general and with regard to specific suggestions mainly on Tim's blog.
Sep 30, 2015 at 21:13 comment added Joel David Hamkins Perhaps you could mention some criteria that have been proposed for what kind of problem would make a good polymath project?
Sep 30, 2015 at 19:13 comment added Gil Kalai I am curious what could be good polymath projects in areas not represented in polymath projects so far which are amply represented over MO like algebraic geometry, algebraic topology, group theory, differential geometry, probability, representation theory, logic and set theory, mathematical physics and various areas of algebra and analysis, and, of course, in various areas of applied mathematics, and connections between mathematics and other sciences.
Sep 30, 2015 at 18:27 comment added Joseph O'Rourke I don't have the freedom to write a careful proposal at the moment, but I believe a project could built around a cluster of tiling problems. In particular: Is the Heech number bounded for polygonal monotiles? Is it decidable to determine if a single given polygonal tile can tile the plane monohedrally? Even for a single polyomino?
