What was discovered

More than 500 pages of new theory that, according to its author, prove the abc conjecture, with enormous consequences for number theory. Published in 2021 in a journal of RIMS itself, it is not accepted as a proof by the international community.

Scholze and Stix pointed out a gap in Corollary 3.12 in 2018, which Mochizuki denies; it is the most notable dispute in mathematics today.

What it led to

  • the debate over verification and consensus in mathematics
  • attempts at formalisation

Built on

  • abc conjecture (Oesterlé and Masser, 1985)
  • anabelian geometry
