EDP28 — problem solved by Terence Tao!

September 20, 2015

I imagine most people reading this will already have heard that Terence Tao has solved the Erdős discrepancy problem. He has blogged about the solution in two posts, a first that shows how to reduce the problem to the Elliott conjecture in number theory, and a second that shows (i) that an averaged form of the conjecture is sufficient and (ii) that he can prove the averaged form. Two preprints covering (i) and (ii) are here and here: the one covering (i) has been submitted to Discrete Analysis.

This post is therefore the final post of the polymath5 project. I refer you to Terry’s posts for the mathematics. I will just make a few comments about what all this says about polymath projects in general.

Discrete Analysis — an arXiv overlay journal

September 10, 2015

This post is to announce the start of a new mathematics journal, to be called Discrete Analysis. While in most respects it will be just like any other journal, it will be unusual in one important way: it will be purely an arXiv overlay journal. That is, rather than publishing, or even electronically hosting, papers, it will consist of a list of links to arXiv preprints. Other than that, the journal will be entirely conventional: authors will submit links to arXiv preprints, and then the editors of the journal will find referees, using their quick opinions and more detailed reports in the usual way in order to decide which papers will be accepted.

Part of the motivation for starting the journal is, of course, to challenge existing models of academic publishing and to contribute in a small way to creating an alternative and much cheaper system. However, I hope that in due course people will get used to this publication model, at which point the fact that Discrete Analysis is an arXiv overlay journal will no longer seem interesting or novel, and the main interest in the journal will be the mathematics it contains.

The members of the editorial board so far — but we may well add further people in the near future — are Ernie Croot, me, Ben Green, Gil Kalai, Nets Katz, Bryna Kra, Izabella Laba, Tom Sanders, Jozsef Solymosi, Terence Tao, Julia Wolf, and Tamar Ziegler. For the time being, I will be the managing editor. I interpret this as meaning that I will have the ultimate responsibility for the smooth running of the journal, and will have to do a bit more work than the other editors, but that decisions about journal policy and about accepting or rejecting papers will be made democratically by the whole editorial board. (For example, we had quite a lot of discussion, including a vote, about the title, and the other editors have approved this blog post after suggesting a couple of minor changes.)

I will write the rest of this post as a series of questions and answers.

The selected-papers network

June 16, 2013

This post is to report briefly on a new and to my mind very exciting venture in academic publishing. It’s called the Selected Papers Network, and it has been designed and created by Christopher Lee. If you want to know what it is and what you can do to help it become a success, then you may wish to stop reading this post and turn straight away to a post by John Baez, who has been closely involved with the venture and understands it better than I do. But let me just briefly mention the main point that has struck me so far.

A problem with the current situation is that it is easy to come up with ideas for websites where people can review papers, complete with clever protocols for how the reviewing should take place, whether it is open, reward systems, etc. etc. It’s much less easy to persuade people to use the sites that are created as a result: what is going to persuade them to make the effort, when there’s only rather a small chance that the site will become in any sense “official”?

The Selected Papers Network potentially solves this problem in a very interesting way: it is not a website with a system for reviewing, evaluating, rewarding etc.. Rather, it is an environment that makes it easy to build your own systems.

Pierre Deligne wins the 2013 Abel Prize

March 20, 2013

I have just finished presenting the work of this year’s Abel Prize winner, who is Pierre Deligne. In due course, the talk will appear on the Abel Prize website. As in the last two years, I have also prepared a written version of the talk, which goes into more detail. However, even the written version leaves a lot out. It was intended for a general — that is, not necessarily mathematical — audience, though I had to assume at least some maths. If your level of mathematical experience means that you find it too elementary, then I have three recommendations for further reading. I found these slides of Kumar Murty about Ramanujan’s tau function helpful and interesting. I also very much like Brian Osserman’s article on the Weil conjectures, written for the Princeton Companion to Mathematics. Finally, Nick Katz did the laudatio for Deligne’s Fields Medal and wrote an excellent article on his work. (Another article that I stumbled on only recently that looks incredibly nice, which is not about Deligne, though it mentions him, but which sheds interesting light on some of Deligne’s work is Finding Meaning in Error Terms, by Barry Mazur. So far I have just skimmed through some of it, but I think I’ll be going back to read it in more detail.)

Why I’ve also joined the good guys

January 16, 2013

For some months now I have known of a very promising initiative that until recently I have been asked not to publicize too widely, because the people in charge of it did not have a good estimate for when it would actually come to fruition. But now those who know about it have been given the green light. The short version of what I want to say in this post is that a platform is to be created that will make it very easy to set up arXiv overlay journals.

What is an arXiv overlay journal? It is just like an electronic journal, except that instead of a website with lots of carefully formatted articles, all you get is a list of links to preprints on the arXiv. The idea is that the parts of the publication process that academics do voluntarily — editing and refereeing — are just as they are for traditional journals, and we do without the parts that cost money, such as copy-editing and typesetting.

EPSRC update update

May 31, 2012

This brief post is to update further a recent post that was itself an update on the situation with EPSRC. The good news is that EPSRC postdoctoral fellowships in mathematics are now available for “intradisciplinary research” (as was already the case with the early career and established career fellowships). I am told that a certain amount of work went on behind the scenes to achieve this: we should be very grateful to the mathematicians involved, and grateful also to EPSRC for being prepared to show a degree of flexibility in this instance. I am also told, though only time will tell how true this is, that the interpretation of the word “intradisciplinary” will be generous, so unless your research is extremely narrow, you should be able to present it in a way that will qualify.

Horizon 2020 to promote open access

May 17, 2012

If you read an earlier post of mine about Elsevier’s updated letter to the mathematical community then you may remember that towards the end of the post I claimed that Elsevier was lobbying heavily to have all mention of open access removed from the documents of Horizon 2020, Europe’s “Framework Programme for Research and Innovation”, a claim that was then denied by Alicia Wise, who is Elsevier’s “Director of Universal Access”.

Leaving aside who is right about this (which may depend rather sensitively on the precise words used to describe what happened, not to mention the interpretation of those words), news has broken today in the THE of potentially important developments. It seems that whatever lobbying Elsevier might have gone in for has been to no avail, because open access will be a very significant aspect of Horizon 2020.

The mathematics department at TU Munich cancels its subscriptions to Elsevier journals

May 4, 2012

A natural way that one might hope to bring about a genuine change to the current subscription model where libraries pay through the nose for journals is that (i) we all put our papers on the arXiv and (ii) the libraries conclude, correctly, that the benefits from their very expensive subscriptions do not justify the costs. Bundling across subjects makes this a lot more difficult of course, but it seems that some institutions in Germany do not subscribe to the Freedom Collection (see previous post for a definition), which makes it easier. And now there is an example. The Technical University of Munich mathematics department has put out an announcement that it will cancel all its Elsevier subscriptions by 2013.

Please, if you are considering submitting a paper to an Elsevier journal without putting it on the arXiv, think of the faculty members of TU Munich who will not be able to get access to your papers (or at least not conveniently), and change your mind. If you do, it will also make it easier for other departments and libraries to make similar decisions.

Polymath paper published

April 23, 2012

I’m glad to be able to report that “A new proof of the density Hales-Jewett theorem” has recently appeared in Annals of Mathematics. Unfortunately it’s behind a paywall, but you can find an almost final version on the arXiv.

I might add that my enthusiasm for this way of working is undimmed. The reason there has been no Polymathematical activity on this blog for quite a while is that I’ve been busy with more conventional projects, but in the not too distant future I’d like to do some more open research. Also, Gil Kalai and I have a plan to try soon to revive the EDP project. I won’t say any more about that now, but it seems a good moment to mention it.

Endre Szemeredi wins the 2012 Abel Prize

March 21, 2012

If you were looking for a clue about this year’s winner, you could perhaps have paid attention to the curious incident of my recent Mathoverflow question.

“But you haven’t asked any Mathoverflow questions recently.”

That was the curious incident.

Anyhow, it was wonderful to be told that Endre Szemerédi was to be this year’s winner. I won’t say any more in this post, but instead refer you to the Abel Prize website and to the written version of the talk I gave, which was intended for non-mathematicians.
