Various Polymath Projects

February 5, 2010 by kristalcantwell

There is new thread for Polymath5. Also the paper “Density Hales-Jewett and Moser numbers” has been submitted to the arXiv. It has been submitted to the Szemeredi birthday conference proceedings. There is time for minor corrections till the final submission in April. I think there is one question still open about the bibliography of the paper.

Let me update this there is a new thread for Polymath5.

More computer problems

February 3, 2010 by kristalcantwell

I am having more computer problems. It looks like I will eventually have to replace the computer to get back on the internet and that may result in a gap in postings here.

New thread for Polymath5

January 31, 2010 by kristalcantwell

There is a new thread for polymath5. One goal that is close to being reached that of deriving a counterexample that is completely multiplicative from any counterexample. Let me update this there is another thread here. It is the fifth thread since the start of the project.

Progress on polymath projects

There is a new thread for Polymath5. Also the paper “Density Hales-Jewett and Moser numbers” will be submitted February 1 to arXiv and to the Szemeredi conference proceedings.

New Thread for Polymath5

January 22, 2010 by kristalcantwell

There is a new thread for Polymath5. It now looks like if there is a quasi-multiplicative sequence of bounded discrepancy then there is a multiplicative sequence of bounded discrepancy.

My computer situation has improved.

Polymath5 officially starts

January 19, 2010 by kristalcantwell

Polymath5 has officially started. There have been some interesting patterns showing up in some of the examples and now some theoretical questions are being asked. The program is roughly to show that every completely multiplicative sequence cannot have bounded discrepancy then show every low discrepancy sequence can be cleaned up to be quasi-multiplicative and then extend the proof that every completely multiplicative sequence cannot have bounded discrepancy to one showing that quasi-multiplicative sequence cannot have bounded discrepancy.

Polymath5

January 17, 2010 by kristalcantwell

There is a new thread for polymath5. There is also this post. There is a sequence of 1124
values of plus or minus one which has discrepancy two. It is exhibiting an interesting pattern which may be generalized to yield an infinite sequence which has sublogarithmic discrepancy.

Density Hales-Jewett and Moser numbers

The deadline for this paper has changed. The deadline has been moved from April to February. See the following post.

Polymath in New York Times

January 14, 2010 by kristalcantwell

In the New York Times magazine’s year in ideas one of the ideas is massively collaborative mathematics and the polymath project is mentioned here is a link

I found this here.

I may be offline for a while. I am having problems with my computer. It may have to be replaced.

New thread for polymath5

January 10, 2010 by kristalcantwell

There is a new thread for polymath5 here. There is also a wiki page for experimental results here. Let me update this there is now a third thread for polymath5 see here. Let me update further there is now a fourth thread. There is also a polymath5 tag on Math Overflow.
