Shinichi Mochizuki (望月 新一, Mochizuki Shin'ichi, born March 29, 1969) is a Japanese mathematician working in number theory and geometry. He is the leader of, originator and one of the main contributors to the branch of modern number theory called anabelian geometry. His contributions include his solution of the Grothendieck conjecture in anabelian geometry about hyperbolic curves over number fields. He initiated and developed several other developments in that area: absolute anabelian geometry, mono-anabelian geometry, and combinatorial anabelian geometry. Among other theories, Mochizuki introduced and developed Hodge–Arakelov theory, p-adic Teichmüller theory, and etale theta function theory.

Shinichi Mochizuki is the author of the inter-universal Teichmüller theory (IUT), also referred to as the arithmetic deformation theory or Mochizuki theory. This theory uses anabelian geometry and his mono-anabelian geometry and etale theta function theories. Due to its nature and applications, IUT has attracted a high level of attention of non-mathematicians.[2] IUT supplies a new conceptual view on numbers by using non-commutative groups of symmetries, such as the full absolute Galois groups and arithmetic fundamental groups and by restoring ring structures.

Biography

Early life

Shinichi Mochizuki was born to parents Kiichi and Anne Mochizuki.[3] When he was five years old, Shinichi Mochizuki and his family left Japan to live in the USA. His father was Fellow of Center for International Affairs and Center for Middle Eastern Studies at Harvard University (1974-76).[4] Mochizuki attended Phillips Exeter Academy and graduated in 1985.[5] He entered Princeton University as an undergraduate at age 16 and graduated salutatorian in 1988.[5] He then received a Ph.D. under the supervision of Gerd Faltings at age 23.[1] After his PhD, Mochizuki spent two years at Harvard and then in 1994 moved back to Japan to join the Research Institute for Mathematical Sciences in Kyoto University (RIMS) in 1992 and was promoted to professor in 2002.[1][6]

Career

Mochizuki proved Grothendieck conjecture on anabelian geometry in 1996. He was an invited speaker at the International Congress of Mathematicians in 1998.[7] In 2000-2008 he discovered several new theories including the theory of frobenioids, mono-anabelian geometry and the etale theta theory for line bundles over tempered covers of the Tate curve.

On August 30, 2012 Shinichi Mochizuki released four preprints, whose total size was about 500 pages, that develop inter-universal Teichmüller theory and apply it to prove several very famous problems in Diophatine geometry, part of number theory.[8] These include the strong Szpiro conjecture, the hyperbolic Vojta conjecture and the abc conjecture over every number field. While there were no experts on IUT in 2012, their number increased to a two-digital one in 2017.[2] The papers are expected to be published in 2018 by Publications of RIMS.[9]
