    $\begingroup$ This conversation is very interesting, but there seems to be a community consensus that we should avoid discussion of the validity of recently announced results. (Also, your post is not really an answer to the question that was asked.) $\endgroup$ Commented Sep 16, 2012 at 10:06

    $\begingroup$ I agree. Let us keep on examining Mochizuki's papers, and hope that his daring but beautiful strategy (deforming, as it were, number fields!) really works. ABC is such a delicate problem: the slightest error in one part of the theory could easily ruin the whole proof (as with Miyaoka's earlier attempt). As for the asymptotic discrepancy with ABC near-misses, Mochizuki himself seems to be a bit perplexed (see the remark on p. 40); hopefully this will be straightened out. $\endgroup$ Commented Sep 16, 2012 at 16:07

    $\begingroup$ If it is completely rewritten, then you should post it as a different answer, because people who upvoted/downvoted your post may change their mind and the relation with discussion in the comments are broken. $\endgroup$ Commented Sep 26, 2012 at 17:11

    $\begingroup$ I think that people are working way, way too hard to define MathOverflow by what it isn't. Although I still like MO, too many babies have been thrown out with various bathwater. This posting by Dimitrov is as important as anything else that I have seen in MO lately. Yet a direct question about the validity of Mochizuki's work was closed down, and then this question was also closed down for a while. (Which may be a valid technical reason to revise an answer instead of posting another one.) What really is the point? It becomes rules just for the sake of rules. $\endgroup$ Commented Sep 27, 2012 at 16:09

    $\begingroup$ Remark about mathematical communication: If Mochizuki's much-publicized papers need revision, then it would be much better for him to post to the arXiv for the sake of public commitment of versions. Preprints that announce important results shouldn't be a moving target. In fact, with his permission it could be done by proxy. $\endgroup$ Commented Sep 28, 2012 at 19:28
