Mini-polymath 4

Mini-polymath 4 has started. It is based on question 3 of the IMO. The research thread is here. There is a wiki here.

New thread for Polymath 7

There has been some progress in the polymath 7 project. See the new thread here.

Polymath 7

Polymath 7 is officially underway. It is here. It has a wiki here. There is a discussion page here.

Polymath Projects

There is a new polymath project on the hot spots conjecture for acute triangles.

It is here.

There is also a mini-polymath coming up. See this post.

Polymath

A paper related to a polymath project has been published. “A new proof of the density Hales-Jewett theorem” will appear in May in Annals of Mathematics. 

Abel Prize

Endre Szemerédi has won  the 2012 Abel Prize.

 

There is a video of the announcement here.

Mini-polymath3

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.

Computer Problems

I am going to working on the computer the next few days. Because of this I may be off the internet.

Mini-Polymath 3

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.

Polymath4

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.
