I read last year that Atiyah thought he had found a proof of the odd order theorem of only 12 pages, using $K$-theory, and that people were trying to figure out if it was correct or not. But I never heard about it afterwards. Did people actually go through it? Was it correct or not?

  • Is that the Feit-Thompson theorem: every group of odd order is solvable? – DonAntonio Jun 11 at 16:33
  • Yes! I edited the question – user404944 Jun 11 at 16:36

    As far as I can tell, it has neither been published, nor put on a public website (such as arxiv). – Lord Shark the Unknown Jun 11 at 17:39

    I was in Heidelberg 2017 where Atiyah was circulating a proof of FT, but reading it with other people we found at least one mistake. I don't recall it involving any K theory, but perhaps my memory fails me. – Pedro Tamaroff Sep 21 at 11:12
