If Atiyah&#8217;s proof holds up, then the nearly 160 year problem concerning the distribution of primes will finally have a solution.\u00a0 It&#8217;s on the\u00a0Clay Mathematics Institute&#8217;s list of seven <a href=\"http:\/\/www.claymath.org\/millennium-problems\/millennium-prize-problems\">Millennium Prize Problems<\/a> and just one of those &#8212; the\u00a0<a href=\"http:\/\/www.claymath.org\/millennium-problems\/poincar%C3%A9-conjecture\">Poincar\u00e9 Conjecture<\/a> &#8212; is listed as solved on the institute&#8217;s website. However, the $1 million prize for a proof of the Riemann hypothesis is yet to be awarded, and some folks doubt that the long-open problem is finally solved.<\/p>\n<p>It&#8217;s unsurprising that the world is watching Atiyah &#8212; and waiting to hear the verdict about the proof he proposed. Atiyah received a\u00a0Fields Medal in 1966. In 2004, he and\u00a0Isadore Singer\u00a0were jointly awarded the Abel Prize for their <a href=\"http:\/\/www.abelprize.no\/artikkel\/vis.html?tid=63119\">discovery and proof<\/a> of the Atiyah-Singer index theorem. Yet many other supposed proofs for the Riemann hypothesis have been proposed, only to fall apart under further scrutiny.<\/p>\n<p>The Clay Mathematics Institute&#8217;s <a href=\"http:\/\/www.claymath.org\/sites\/default\/files\/official_problem_description.pdf\">&#8220;Official Problem Description&#8221;<\/a> for the Riemann hypothesis is 11 pages long (with nearly two full pages of references), while Atiyah&#8217;s current <a href=\"https:\/\/drive.google.com\/file\/d\/17NBICP6OcUSucrXKNWvzLmrQpfUrEKuY\/view\">write-up<\/a> of the proof is five pages long. &#8220;Atiyah attributes much of the theoretical work that underpins the proof to a paper of his own that has been submitted to the\u00a0<cite>Proceedings of the Royal Society A,&#8221;\u00a0<\/cite>Frankie Schembri <a href=\"https:\/\/www.sciencemag.org\/news\/2018\/09\/skepticism-surrounds-renowned-mathematician-s-attempted-proof-160-year-old-hypothesis\">wrote<\/a> for Science. &#8220;That paper has yet to be published,&#8221; she added. In fact, Atiyah&#8217;s list of references includes just three works: the aforementioned unpublished paper, his 2018 Abel lecture at the ICM in Rio de Janeiro and\u00a0Friedrich\u00a0Hirzebruch&#8217;s 1966\u00a0<em>Topological Methods in Geometry<\/em>.<\/p>\n<p>News of Atiyah&#8217;s claim has reached far and wide since his announcement.

He wrote &#8220;I bet that Atiyah&#8217;s claimed proof&#8230;will not convince experts.\u00a0In 2017 he claimed to have a 12-page proof of the Feit-Thompson theorem, which usually takes 255 pages:\u00a0https:\/\/www.maths.ed.ac.uk\/~v1ranick\/atiyahtimes2017.pdf.\u00a0<\/span><span class=\"s2\">He showed it to experts, and&#8230; silence.&#8221; What&#8217;s more, &#8220;In 2016 Atiyah put a paper on the arXiv claiming to have solved a famous problem in differential geometry. The argument was full of big holes: <a class=\"twitter-timeline-link\" title=\"https:\/\/mathoverflow.net\/questions\/263301\/what-is-the-current-understanding-regarding-complex-structures-on-the-6-sphere\" href=\"https:\/\/t.co\/STpqByhBMG\" target=\"_blank\" rel=\"nofollow noopener\"><span class=\"invisible\">https:\/\/<\/span><span class=\"js-display-url\">mathoverflow.net\/questions\/2633<\/span><span class=\"invisible\">01\/what-is-the-current-understanding-regarding-complex-structures-on-the-6-sphere<\/span><span class=\"tco-ellipsis\"><span class=\"invisible\">\u00a0<\/span>\u2026<\/span><\/a> So, I&#8217;m not holding my breath this time.

I have a bad feeling about this. Famed mathematician Michael Atiyah claims proof of Riemann hypothesis,&#8221; along with a link to the September 21 <a href=\"https:\/\/www.newscientist.com\/article\/2180406-famed-mathematician-claims-proof-of-160-year-old-riemann-hypothesis\/#.W6UzU01bMiw.twitter\">New Scientist article<\/a> about Atiyah&#8217;s claimed proof. When asked by Twitter user <a href=\"https:\/\/twitter.com\/horrocks_jon\">Jonathan Horrocks<\/a> &#8220;Why bad? I take anything Atiyah says very seriously,&#8221; Strogatz responded &#8220;I take him seriously too. It\u2019s the same bad feeling I have when a diver attempts an extremely difficult dive: afraid, yet hoping for success.&#8221;<\/p>\n<p>The skepticism surrounding the claimed proof doesn&#8217;t appear to faze Atiyah. &#8220;Nobody believes any proof of the Riemann hypothesis, let alone a proof by someone who\u2019s 90,&#8221; he said to Gilead Amit\u200b, author of the New Scientist article. &#8220;People say \u2018we know mathematicians do all their best work before they\u2019re 40,'&#8221; Atiyah said, adding &#8220;I\u2019m trying to show them that they\u2019re wrong. That I can do something when I\u2019m 90.\u201d<\/p>\n<p>Regardless of whether Atiyah&#8217;s proof holds, he has already done something phenomenal: reignited a worldwide conversation\u00a0about the Riemann hypothesis. That alone is something to celebrate.<\/p>\n<p>What do you think? Share your thoughts in the comments below or reach out to me on Twitter @writesRCrowell!
