Shinichi Mochizuki (望月 新一 Mochizuki Shin'ichi?, born March 29, 1969) is a Japanese mathematician specializing in number theory. He worked in arithmetic geometry and such of its areas as Hodge theory, anabelian geometry. He introduced p-adic Teichmüller theory, Hodge–Arakelov theory, the theory of Frobenioids and mono-anabelian geometry. In 2012 he released his work on new inter-universal Teichmüller theory (IUT) which essentially extends the scope of arithmetic geometry.

Mochizuki was an invited speaker at the International Congress of Mathematicians in 1998.[2]

Mochizuki proved Grothendieck conjecture on anabelian geometry in 1996.[3] In 1999, he introduced Hodge–Arakelov theory and in 2008 he introduced Frobenioids. In 2012, he introduced Inter-universal Teichmüller theory which is an arithmetic version of Teichmüller theory for number fields endowed with an elliptic curve.

In August 2012, Mochizuki released four preprints which develop inter-universal Teichmüller theory and also its applications to proof of several famous conjectures in diophantine geometry,[4] including the abc conjecture. The theory is very complex and involves many novel concepts and objects. It has already been verified more than 10 times by several mathematicians and more mathematicians are studying it. [5]

Mochizuki documented the relevant progress in two reports, the first in December 2013 and the second in December 2014.

Life[edit]

When he was five years old, Shinichi Mochizuki and his family left Japan to live in New York City. Mochizuki attended Phillips Exeter Academy and graduated in 1985.[6] He entered Princeton University as an undergraduate at age 16 and graduated salutatorian in 1988.[6] He then received a Ph.D. under the supervision of Gerd Faltings at age 23.[1] He joined the Research Institute for Mathematical Sciences in Kyoto University in 1992 and was promoted to professor in 2002.[1]

Inter-universal Teichmüller theory[edit]

As of December 2014, through discussion with Y. Hoshi and G. Yamashita of the Research Institute for Mathematical Sciences in Kyoto University and M. Saidi of University of Exeter, Mochizuki wrote "I have yet to hear of even a single problem that relates to the essential thrust or validity of the theory" on the progress report.[7] According to Mochizuki, "At least with regard to the substantive mathematical aspects of such a verification, the verification of Inter-universal Teichmüller theory is, for all practical purposes, complete".[8] He wrote, however, "Nevertheless, as a precautionary measure, in light of the importance of the theory and the novelty of the techniques that underlie the theory, it seems appropriate that a bit more time be allowed to elapse before a final official declaration of the completion of the verification of Inter-universal Teichmüller theory is made."[8]

A workshop on IUT was held at RIMS in March 2015. A workshop of Clay Mathematical Institute on the theory of Mochizuki is scheduled for December 2015.
