TITLE: Have there been any updates on Mochizuki's proposed proof of the abc conjecture?
QUESTION [67 upvotes]: In August 2012, a proof of the abc conjecture was proposed by Shinichi Mochizuki. However, the proof was based on a "Inter-universal Teichmüller theory" which Mochizuki himself pioneered. It was known from the beginning that it would take experts months to understand his work enough to be able to verify the proof. Are there any updates on the validity of this proof?

REPLY [29 votes]: Today (3 April 2020) his papers have been accepted for publication on RIMS journal.
