It looks like Vesselin has located a serious âred flagâ in Mochizuki's argument, in that the main Diophantine inequality claimed in IUTT-IV appears to have a robust family of counterexamples (assuming the truth some plausible conjectures, including abc): http://mathoverflow.net/questions/106560/philosophy-behind-mochizukis-work-on-the-abc-conjecture/107279#107279
This doesn't tell us exactly where the source of the error is coming from, though, or how fixable it would be. But it would be difficult to be optimistic about the proof until this issue is somehow resolved.

Itâs mainly quiet at the moment, apart from a claimed set of counterexamples to one of Mochizukiâs intermediate theorems posted by Vesselin Dimitrov on MathOverflow, which was quickly shut down because the community there didnât approve of MO being used to debate the validity of the proof. No doubt there are other niggles being worked out in private as well.
