As you may remember from an earlier post on this blog, Discrete Analysis is a new mathematics journal that runs just like any other journal except in one respect: the articles we publish live on the arXiv. This is supposed to highlight the fact that in the internet age, and in particular in an age when it is becoming routine for mathematicians to deposit their articles on the arXiv before they submit them to journals, the only important function left for journals is organizing peer review. Since this is done through the voluntary work of academics, it should in principle be possible to run a journal for almost nothing. The legacy publishers (as they are sometimes called) frequently call people naive for suggesting this, so it is important to have actual examples to prove it, and Discrete Analysis is set up to be one such example. Its website goes live today.

### Discrete Analysis launched

March 1, 2016### Interesting times in academic publishing

November 10, 2015In this post I want briefly to mention four current goings on in the world of academic publishing.

First, I’ll just briefly say that things are going well with the new journal Discrete Analysis, and I think we’re on course to launch, as planned, early next year with a few very good accepted papers — we certainly have a number of papers in the pipeline that look promising to me. Of course, we’d love to have more.

Secondly, a very interesting initiative has recently been started by Martin Eve, called the Open Library of Humanities. The rough idea is that they provide a platform for humanities journals that are free to read online and free for authors (or, as some people like to say, are Diamond OA journals). Perhaps the most interesting aspect of this initiative is that it is funded by a consortium of libraries. Librarians are the people who feel the pain of ridiculous subscription prices, so they have great goodwill towards people who are trying to build new and cheaper publication models. I think there is no reason that the sciences couldn’t do something similar — in fact, it should be even easier to find money.

### EDP28 — problem solved by Terence Tao!

September 20, 2015I 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, 2015This 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.

### What I did in my summer holidays

October 24, 2013This post is intended to accomplish several things at once. First and foremost, I want to explain (not just in the post) why I have been interested in Borel determinacy and in the natural proofs barrier. Roughly speaking (or should I say tl;dr?) I think that Martin’s proof of Borel determinacy has features that might just conceivably offer a way past that barrier.

As long-term readers of this blog will be aware, the P versus NP problem is one of my personal mathematical diseases (in Richard Lipton’s sense). I had been in remission for a few years, but last academic year I set a Cambridge Part III essay on barriers in complexity theory, and after marking the essays in June I thought I would just spend an hour or two thinking about the problem again, and that hour or two accidentally turned into about three months (and counting).

The trouble was that I had an idea that has refused to die, despite my best efforts to kill it. Like a particularly awkward virus, it has accomplished this by mutating rapidly, so that what it looks like now is very different from what it looked like at the beginning of the summer. (For example, at that stage I hadn’t thought of trying to model a proof on the proof of Borel determinacy.) So what am I to do?

### Why I’ve also joined the good guys

January 16, 2013For 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.

### Why I’ve joined the bad guys

January 14, 2013A few months ago I was alerted by a pingback to the existence of a blog post by Orr Shalit entitled Worse than Elsevier which included the assertion that Terence Tao and I had “joined the bad guys”. That is an allusion to the fact that we are editors for Forum of Mathematics, CUP’s new open-access journal. This post serves a dual purpose: to draw attention to the fact that Forum of Mathematics is now accepting submissions, and to counter some of the many objections that have been raised to it. In particular, I want to separate out the objections that are based on misconceptions from the objections that have real substance. Both kinds exist, and unfortunately they tend to get mixed up.

If you are not already familiar with this debate, the aspect of Forum of Mathematics that many people dislike is that it will be funded by means of article processing charges (which I shall abbreviate to APCs) rather than subscriptions. For the next three years, these charges will be waived, but after that there will be a charge of £500 per article. Let me now consider a number of objections that people have to APCs.

### A new open-access venture from Cambridge University Press

July 2, 2012The formal launch has just taken place at the European Congress of Mathematicians in Krakow of the Forum of Mathematics, which to a first approximation is a new open-access electronic journal. However, the singular “journal” is misleading, because in some ways it is more like a whole set of journals. But there will be considerable interdependence between the elements of the set, so “journals” is misleading too. We need an intermediate number between singular and plural. Also, although the journal(s) is/are primarily electronic, there will be a print-on-demand option if anyone wants it.

**What is the Forum of Mathematics?**

Terminological questions aside, how will this new journal-like object work? I think the easiest way of explaining it is to describe the process for submitting an article, which is similar to the process for submitting an article to a conventional maths journal, but with one or two unusual aspects.

### What’s wrong with electronic journals?

January 29, 2012It probably sounds disingenuous of me to say this, but when I sat down to write a post about Elsevier I wasn’t really trying to start a campaign. My intention was merely to make public, and a little more rigid, a policy that I and many others had already been applying, in my case without much difficulty, for several years. The idea of setting up a website occurred to me as I was writing the post: I considered it (and still consider it) not as a petition to Elsevier to change its ways — since I don’t believe there is any realistic chance of that — but as a simple way to bring out into the open all the private boycotts and semi-boycotts that were going on, and thereby to encourage others to do the same.

By accident, the post seems to have been quite well timed. Probably it’s not an accident at all, and that whatever atmosphere it was that prompted me to get round to writing the post (for example, certain discussions I had had with other mathematicians, some of them online) was the same as what made it a good moment. Anyhow, accident or no, the result is that some people have talked about “momentum”, and I’m starting to feel a responsibility, not particularly welcome (because it threatens to involve work), not to squander that momentum.

### A more modest proposal

November 3, 2011In my previous post I suggested a way in which an online system of submitting and commenting on papers might perhaps work better than our current system of journals, editors and anonymous referees. I am very grateful to all who commented, both positively and (more often) negatively. It has given me a lot to think about. One thing that I wasn’t expecting, but should have expected, was that a number of people just plain don’t like the idea of an online alternative, regardless of the rational arguments. I don’t mean that there aren’t arguments to back up the dislike — merely, that I think that there is a dislike there, which becomes an argument in itself, since if many people have an emotional reaction against a new system, then that makes it less likely that the system will be adopted by enough people to become as officially recognised as the journal system. To avoid misunderstanding, let me stress that I’ve got nothing against emotional reactions, as long as they are backed up with arguments; and in the comments on my previous post they have been. Indeed, the arguments against various aspects of what I suggested have caused me to realize that there are some disadvantages I didn’t think of and others that I underestimated.

In this post, I want to summarize the points made in the comments (for the benefit of anyone who is interested in what was said but doesn’t have time to read through them all), and then make a second suggestion, which I think deals with a number of objections to the first. As with the first, I don’t see the details as set in stone. I think it’s an improvement on the first, but doubtless it can itself be improved on. Whether it reaches the level where one should actually consider trying to implement it is of course quite another matter. But I do think that these issues should be discussed: if we were designing a system from scratch for disseminating and evaluating mathematical output, I don’t think we would come up with the current journal system, though of course that’s not the situation, and historical accidents often result in quite good ways of doing things.
