I was wondering if there are any websites out there which

  • systematically provide space for the discussion of mathematics articles (particularly those on the arXiv, though not necessarily just those), and
  • have a large enough user base to have some hope of having a good discussion (or at least have hope of attracting one in the near future).

Of course, MO is not so far from such a site, but is organized around questions, not papers, which leads to rather different discussion in practice. Similarly, some blog posts and nLab pages serve this purpose, but are not created systematically.

    $\begingroup$ Maybe the question is not appropriate for MO, but Andy Putnam's and Yemon Choi's comments don't make sense. Obviously there are innumerable forums for discussion of anything, but if it were universally known that for each arXiv paper there is an accompanying discussion page (which need not exist before someone actually decides the particular paper is worth discussing) then everyone on the planet interested in discussing a particular paper would be gathered together in the same internet forum: that particular paper's discussion page. The department tea room can't do that. $\endgroup$

    $\begingroup$ @Andy: you make a self-fulfilling prophecy. There are 100s of people who would like to participate (a handful of which are also capable), but they are forever locked out of "the community" because of location, inability to travel, intimidated by BIG NAMES. They can't become part of the community because they aren't already part of the community. $\endgroup$

    $\begingroup$ @Andy: Sorry about the spelling. The number of people wishing to discuss most papers would be zero, I would think. In those cases no discussion page would be created. It's the ones that several people want to discuss that matter. You say most of those people know each other. Do you know most of the people who discuss things with you on MO? People wishing to discuss the same paper who've never heard of each other would communicate on such pages. What would happen with most pages (no discussion) is beside the point. $\endgroup$

I'm pretty sure the answer to the question as asked is "No". At present there does not seem to exist a unique web location dedicated to discussing each individual mathematical article.

It would be technically feasible, and to my mind advantageous, to set up a "talk" page attached to each arXiv article. I have seen this suggestion on various mathematical blogs (unfortunately, I can't remember which ones, and googling doesn't turn them up; this answer, like the question, is CW, so if you know of any, please just include a link). I certainly do not know enough about web design to draft such a system, and the folks who run the arXiv do, but are horribly overworked as it is, so I doubt that they'll be writing anything anytime soon. I encourage others with massive web-fu to create some code and send it towards the arXiv administrators, but they might not even have the time to look at it. (When you are thinking about how best to set up such a site, please do keep in mind that well-working online forums tend to have fairly heavy moderation. Moderator attention is definitely not sufficient to have a well-run site, and not strictly necessary, but it helps. Since there aren't nearly enough people out there eager to moderate random columns on the arXiv, one proposal I've seen is for arXiv authors to have the option to open a talk page, with the commitment that they themselves participate and moderate.) (Another thing to think about is how to convince NSF to fully underwrite the costs at arXiv.)

Note that although most mathematics papers are available on arXiv, it is not the only database of papers. I could imagine adding a talk page to each bibliographic entry at Numdam, for example, or to each article at Web of Science.

Something like a "talk" page does exist for (almost) every (published) mathematical article, but I don't think it's what the question is after. MathSciNet and Zentralblatt include reviews of every (almost) article in their databases, written by experts. This does not accomplish the goal of "systematically provid[ing] space for the discussion of mathematics articles", but it is something.

    $\begingroup$ If arxiv papers had to have a talk page, it would allow anyone to criticize a paper and the author would likely feel compelled to respond. Given the type of "commentary" you see on most web forums, including math forums, I think this would just drag down the arxiv and a lot of people would even stop using it. I can see myself stop putting papers on the arxiv if I had to deal with random internet people with an opinion and arxiv access. And even if it were made optional, many people would still voluntarily use it and the same type of thing would still go on. $\endgroup$

    $\begingroup$ In a sense the arXiv does have a way for users to comment on papers, as there is a "track-back" feature where any time an arXiv paper is mentioned on a specific family of blogs and webpages, the arXiv keeps track of it. For example, this forum is one such location that that arXiv tracks back to. $\endgroup$

    $\begingroup$ One side effect of having an automatic talk page for every paper is that it will make authors realise just how tiny the audience for their papers really is. I post about my own papers on my blog and these are reliably the least viewed and least commented upon articles on my site. This is fine with me - the comments that I do get are often of extremely high quality (and also supply some valuable corrections and references) - but it is likely that many authors may overestimate, at least initially, the magnitude of impact that any of their papers will have. $\endgroup$

Although no such system exists formally (as far as I know) there is an informal way to do this. Namely make some comments on a blog or web page and then add a trackback to the arXiv page. If this happened on a regular basis then it could be developed into something more systematic along the lines you are suggesting. My feeling is that only a small percentage of papers would attract any discussion.

I think this is a very reasonable question. It comes up often enough and deserves an answer. In fact, I see not one but two potential forums. Here is my take.

1) Rumors, followup ideas, small errors, minor comments and remarks on the paper. This is all worth doing on your own blog space. I see no need to make this kind of discussion "official". In fact, the diversity of blogs and opinions is a plus here: less "intimidation by experts", fewer worries about "degeneration" of the discussion, etc. Finally, typos and mistakes in the paper are responsibilities of the author - when you find them, email them to her/him and stop worrying about other readers. In short, I see no need for a single forum for a discussion of this kind.

2) Serious comments, substantial remarks, delicate technical problems with the paper, etc. I think a blog or wiki type discussion forum is a too informal/unserious for contributions of this kind. On a positive side, there is a perfect forum for this kind of discussions: it's called the arXiv! Remember, the arXiv was never meant to be a only a "free storage" of published papers. It has moderators, calls uploaded papers "submissions", and once approved, calls them "publications". A great feature of arXiv is that you can store and advertise there the kind of work that you don't intend to publish in traditional journals. So if you have something important to say to everyone, don't be shy, follow Mnёv's example and post it on the arXiv (here are some other examples). Make sure to add hyperlinks to older arXiv papers if you want it to look more webby. Finally, there is already a great tool to explore forward arXiv citations. So why bother inventing a new forum when the one we have works fine, if only people used it more often for this purpose.

It seems appropriate to mention Gowers's "Modest Proposal" from fall of 2011. Here is his original post, and then his "more modest proposal." This came about after the OP asked this question and seems very related, since a big benefit of his recommended mathoverflow-like system of submitting papers was the ability to have discussions of those papers. As others have pointed out, this also allows the community to quickly correct errors in the papers and also would reduce the lag-time between when new results are finished and when others can start to build on those results. I'm not sure what ever happened to Gowers's idea, except that there was a lot of discussion at the time and problems were pointed out. If someone knows, I hope he/she will edit this and fill in the details. This also seems related to Alex Chernov's recent answer; maybe Furmaniak's site was based on Gowers's ideas. I'm not really familiar with Reddit, so I don't know how similar it is to what Gowers envisioned.

PaperHive seems to fulfill both of your requirements, as far as I have seen. It provides a discussion channel directly next to the document (or in a seperate tab) to ask questions and comment on marked test passages, or to ask for clarifications.

Since arXiv is open access, one can look at most of the arXiv articles on PaperHive, as they are synced with PaperHives frontend. Just search for something, you can even use arXiv ID or DOI for some journals that are available. Most other things look self-explanatory.

A big counter-argument against PaperHive as a discussion board for arXiv articles is that there seems to be a lack of availability of arXiv articles newer than 2016. Maybe that is because of the lack of interest, but it is hopefully easy to fix. I just discovered this problem while writing this.

I'm surprised no one here has heard of it before, it has been around for four years now. It just has no big user base of mathematicians. I still see potential in the concept, and a lot of code for PaperHive has been made open source.
