I just made a question in MO to discuss the correctness of the proof provided by Prof. Atiyah for the Riemann hypothesis (link here: Is there an error in the pre print published by Atiyah with his proof of the Riemann hypothesis? ). I understand that's usually outside the scope of MO, but this time is the work of an Fields medalist claiming to solve one of the most important math problems currently. Is there a way to reword my question so it could be discussed here? In case the answer is negative, could someone provide a forum with similar quality where such proof could be discussed? Thanks and sorry for the problems caused.

    $\begingroup$ Héctor, I think this one is for the blogs, if anyone wants to take it up. Atiyah has done some of the greatest mathematics in the past 50+ years, but it looks very likely that here he's "not even wrong", and it is for this very reason that he should be accorded some dignity in view of his epoch-making past work -- not a public raking at MO. That's just my opinion. $\endgroup$

    $\begingroup$ The New Scientist article said it best: "New Scientist contacted a number of mathematicians to comment on the claimed proof, but all of them declined." I don't think the professional mathematics community wants to go near this, for good reason. It's a sad situation. If you really want to discuss that preprint, try a more general forum like Reddit r/math. $\endgroup$

I work in an engineering school and today already several faculty members have asked me about Atiyah's proof of the Riemann hypothesis, having read about it online. It's important that the underlying situation (whatever it is - although I can guess, I do not know) be made clear, so that the reputation of a great mathematician is not damaged, and the credibility of the mathematical community is not adversely effected. $\endgroup$

    $\begingroup$ "but someone somewhere has to go on record discussing the claims" There isn't much to discuss, sadly. If you want somebody on record for MO, I can say it openly that the properties of $T$ are self-contradictory. As to the general public opinion and "conspiracy theories" I couldn't care less: we may be living in a "public era" but our craft has none of these two words in its vocabulary. As to "damage to the reputation", IMHO, all of it goes to the HLF organizers and if somebody asks me, I wouldn't hesitate even a second to attribute it there. $\endgroup$

He claimed two years ago that 6-sphere has no complex structure: arxiv.org/abs/1610.09366 . I never saw a professional statement from some prominent geometer that this paper is wrong. I think that trying to keep this situation under the carpet will be damaging for the math community on many levels. Some people all over the globe will spend time reading the text. A duty of math community will be to repeat $10^{10}$ times that the paper is wrong (I guess) $\endgroup$

After some internal discussion, the moderators have agreed to post the following text.

There are calls from the community to enunciate a firm and consistent policy for what questions are permissible or not regarding Atiyah's attempted proof of RH.

If for a moment we blind ourselves to the name on the paper, the natural and appropriate reaction would be to dismiss it out of hand, without fuss and without worry that we were missing out on anything. In the name of consistency, I think that would be the right reaction here as well, and that should really be the policy. So any question that asks for responses on whether this is right or wrong, or if there is something there, should be treated in the way it's always been treated: we at MO do not vet papers that purport to solve famous open problems. And in the case of 5-page articles that announce a solution of RH: we don't discuss them at all. The question will be closed.

My personal opinion is that the situation and the appropriate reaction is made only slightly more complicated by knowing it was Atiyah. There are indeed allusions to sophisticated concepts such as the Todd genus (there is a "Todd function" which is somehow related to the Todd genus). Careful and precise questions about such concepts, at a professional level, are always in principle allowable, and they may mention that some such concept was spotted in Atiyah's article, but these should not turn into cover for discussing the current topic.

We don't think it's possible to spell out policy in advance that will cover every such circumstance; some matters have to be treated on a case-by-case basis, with input from the community. (What's the expression? "Hard cases make bad law"?) Please: just be prudent, and avoid drama.

We have no doubt there will be those who cry "censorship!", "suppression of free thought!", etc. Or, less dramatically: how do you know there's nothing there? Well, none of us know for a fact, and obviously Atiyah's track record from when he was in his prime will give some people pause: for many years he has led mathematicians across difficult country. There may well be a tragic aspect to what is unfolding before us. Let's please preserve some dignity for the man.

Don't worry: if there is truly mathematical takeaway, it will be picked up by the experts. RH will never be solved in a day: any serious solution will take months or years to be pored over and analysed by thousands at home, in offices, in seminar rooms around the world. MathOverflow, especially where it is vulnerable to regrettable social media contaminants, can not play all the necessary roles here. We do not have to be the public bulwark against the conspiracy theorists. Let's keep doing what we do best: provide a clearinghouse to deal with well-circumscribed, sober mathematical questions that can be authoritatively addressed in less than three pages.

Any general public statements we want to make for now can go on this Meta page. If the mathematics begins to look serious, then well-delineated parts can be discussed at Main.

$\begingroup$

I will take a different viewpoint than some and say that the correctness of the proof can be discussed, and maybe it should. But as to how, that's a question of tactfulness and precision.

  • When discussing this proof, it's incredibly important to avoid ad-hominem attacks, benevolent and malicious ones alike. Many people say stuff like "Atiyah has output a lot of unaccepted work in the last years, this is going to be no better" or "He is a Fields medalist for crying out loud, his word is holy!". Both is unacceptable here.
  • Asking about the proof as a whole might be too broad. It's possible to ask well-defined questions like this one about aspects of the proof.
  • Waiting for some time is entirely fine. Put questions on hold until the emotions have cooled down. Math is eternal.

    $\begingroup$ @none I think that interpretation is very uncharitable towards both Heidelberg and the arxiv. Why should they apply the same criteria? They're completely different fora. A simple counterproposal: maybe Atiyah's paper was judged to look less like a fully fleshed-out preprint (because it wasn't) and more like a rough outline of / advertisement for a talk (because it was). Thus it was rejected as a preprint and accepted as a talk. Heidelberg may want to revise its criteria for acceptance after this, but we have no reason to doubt that they were applied fairly, consistently, and in good faith. $\endgroup$

    $\begingroup$ Billy and Zubin, at least for established researchers, the arxiv is basically a self-publishing outlet where you upload your paper with no editorial review at all, and it becomes available to everyone on the server. So if they reject something it reflects an unusual situation (Atiyah's recent activities in this case) that HLF also had to be aware of. HLF still accepted the talk and promoted it on their twitter, which came across to some of us as cheap sensationalism, using Atiyah's fame and the claimed RH result to draw attention to their conference without regard to the consequences. $\endgroup$

I'm not sure I want to believe that the arxiv moderators are in the business of prematurely retiring mathematicians whose work has slipped. I'm far more inclined to believe that it was rejected from the arxiv because e.g. it was sketchily written and grossly under-referenced, not for reasons of mathematics, and that HLF accepted it on the basis of (misplaced but good-faith) trust in the mathematical claims. No contradiction there. $\endgroup$

I don't think there's any good solutions here, but I am going to suggest what I think is the least bad solution, and people can vote on whether it is a good idea or not. There are going to be lots of well-meaning people who want to give Atiyah the benefit of the doubt and are going to ask questions about the proof, so I think leaving it unaddressed on the Math Overflow front page will be difficult to sustain.

I suggest we create a new question that is Community Wiki just for this topic (and Atiyah's fine structure constant paper, since it seems to be related), and close any other questions about it as a duplicate of this question. Then the moderators carefully moderate the question. We avoid any discussion of Atiyah as a person, but people are free to post answers that address the correctness of either paper.

I think the questions are ill timed. Andrew Wiles claimed to have a proof of Fermat's Last Theorem in 1993. It turned out he was wrong, and that it took (at least) weeks of work to produce a proof that is now part of the literature. Wiles deserved and got recognition for the amount of effort he put in and results he got out, even in 1993, but the public (and even most mathematicians) would not understand or appreciate what he did up to that year. If the masses need to understand anything, it is that it takes time to turn claims of a proof into something that properly belongs to the literature.

I think Sir Michael Atiyah has some ideas worth hearing. For reasons personal to me, I do not want to hear them from Sir Michael directly. I do not want to even see them on MathOverflow until they have gone through a filter that makes their presentation suitable for this forum. That means someone other than Sir Michael finds a way to present the ideas, or parts of them, in a fashion that is more clear, more self contained, and more about the math than the media. The recent questions are reasonable ones to ask after enough time has been given to apply such a filter. This means days at a minimum.

    $\begingroup$ I downvoted because I thought the post showed unjustified optimism about the papers' math content, leading to an imho unrealistic prescription for how the situation should play out. That said, Gerhard was at the ICM talk so he may well be better attuned than I am. $\endgroup$

    $\begingroup$ I didn't downvote. I think Gerhard was just trying to be polite and cautious here and so may have come across as hedging. And indeed, having a really open conversation here is pretty uncomfortable. $\endgroup$

  • $\begingroup$ I can think of three down voting plausibilities. The Atiyah fans do not like my not wanting to hear from Sir Michael directly, so downvote. The people who are not signature fans do not like my use of signature to suggest things, so downvote. Finally, the people who enjoy rapid fire gossip may dislike my suggestion to wait days before asking such questions, so downvote.

    $\begingroup$ I downvoted, not out of any ill will, simply because I don't think it really answers the question. I agree with Gerhard on e.g. what "the masses" should understand about mathematics - I just don't think that should have any bearing on what's allowed to be discussed on MO. More importantly, I'm finding it hard to read through the hedging: I agree that content on MO should be suitably presented (obviously!), but the OP's question is: what does a "suitable" presentation look like, and why have previous questions been unsuitable? "Wait at least a few days" is great advice, but not an answer! $\endgroup$

  • $\begingroup$ I have not watched the video, but I understand that not enough was given at the lecture yesterday to be judged as a complete proof, and that even as a sketch some key components are absent. So where is the proof the question asks us to judge? Even if the proof was given on Monday, how long should it take to understand? These MathOverflow questions are inspired by media announcements, not by a proper presentation. At least the question on Todd functions (operators?) is based on an articulated idea.

  • $\begingroup$ @Lspice, it may be for you. Since I don't have a twitter feed, you will have to check my user pages (yes, pages) for "all actions" under activity for earlier examples. Gerhard "Might Triple Nest This Year" Paseman, 2018.09.25. $\endgroup$

    $\begingroup$ The question on this Todd function is precisely the one I had in mind - e.g. because the introduction of the Todd function was not new during the lecture, and it's appeared in the literature at least twice before. Certainly, the answer to that question may end up being "wait for it", but there's absolutely no reason that we have to wait in order to ask the question, which is what your answer suggests. It's a very good question. I think we can be sensitive to this scenario without calling for a moratorium on all related mathematical discussion. $\endgroup$

  • $\begingroup$ Anyway, I don't intend to argue over it. I don't feel that strongly about it. I just wanted to give some insight as to why I downvoted, since someone asked. $\endgroup$
