The mini-polymath3 was today. Here is the research thread.

The wiki is here. There is a discussion thread here.

There was a solution after 74 minutes.

There will be a mini-polymath project around July 19th. There is a poll on the possible starting time here.

I am still having computer problems so my posts may be sporadic for the next couple of months.

Let me update this. The time of the mini-polymath will be

July 19 8pm UTC. That is 1pm July 19, Los Angeles time. I found that out here. Also see this post.

The proofs for the article “Deterministic methods to find primes” will appear in Mathematics of Computation but not with a pseudonym. Apparently Mathematics of Computation had a problem with that. The authors will be Ernie Croot, Harald Helfgott and Terence Tao. See this post.

There was a discussion about polymath projects some of it was described here.

There was an article in the Atlantic about Math Overflow. It mentions the Polymath project. It is available here.

In _the Best Writing on Mathematics: 2010_ there is an article “Massively collaborative mathematics” by Timothy Gowers and Michael Nielsen.

the book _Ramsey Theory: Yesterday, Today, and Tomorrow_ contains an article about Euclidean Ramsey theory “Open problems in Euclidean Ramsey theory” by Ronald Graham and Eric Tressler. it is available here.

Finally there is an article “Memories of Martin Gardner” which appeared in the Notices of the AMS, volume 58, Number 3. It is available here.

There is a counterexample to the Hirsch conjecture in 20 dimensions. The lowest number of dimensions that I was aware of previously was 23. See this post. Also There is a web page here, a poster for the IPAM conference here.

The IPAM congress also has a couple of presentations

related to polymath3. The IPAM congress schedule is here. There are two talks related Polymath3. One abstract is here, the other here.

There is a new thread here. It is the fifth thread for this project.
