> When an error in one of the articles was pointed out by Vesselin Dimitrov and Akshay Venkatesh in October 2012, Mochizuki posted a comment on his website acknowledging the mistake, stating that it would not affect the result, and promising a corrected version in the near future.[15] He revised all of his papers on "inter-universal Teichmüller theory", the latest of which is dated November 2014.[11] Mochizuki has refused all requests for media interviews, but released progress reports in December 2013[16] and December 2014.[17] According to Mochizuki, verification of the core proof is "for all practical purposes, complete." However, he also stated that an official declaration shouldn't happen until some time later in the 2010s, due to the importance of the results and new techniques. In addition, he predicts that there are no proofs of the abc conjecture that use significantly different techniques than those used in his papers.[17] There was a workshop on IUT at Kyoto University in March 2015 and another one will be held at Clay Mathematics Institute in December 2015.[18] http://en.wikipedia.org/wiki/Abc_conjecture#Attempts_at_solution http://en.wikipedia.org/wiki/Abc_conjecture#Attempts_at_solu...
