Shigefumi Mori (森 重文,Mori Shigefumi; born February 23, 1951) is a Japanesemathematician, known for his work inalgebraic geometry, particularly in relation to the classification ofthree-folds. He won theFields Medal in 1990.
Mori completed his Ph.D. titled "The Endomorphism Rings of Some Abelian Varieties" underMasayoshi Nagata atKyoto University in 1978.[1] He was a visiting professor atHarvard University during 1977–1980, theInstitute for Advanced Study in 1981–82,Columbia University 1985–87 and theUniversity of Utah for periods during 1987–89 and again during 1991–92. He has been a professor atKyoto University since 1990.
He generalized the classical approach to the classification ofalgebraic surfaces to the classification of algebraicthree-folds. The classical approach used the concept ofminimal models ofalgebraic surfaces. He found that the concept ofminimal models can be applied tothree-folds as well if we allow somesingularities on them. The extension of Mori's results to dimensions higher than three is called theminimal model program and is an active area of research in algebraic geometry.
He has been elected president of theInternational Mathematical Union, becoming the first head of the group from East Asia.[2]
He was awarded theFields Medal in 1990 at theInternational Congress of Mathematicians.
In 2021, he received theOrder of Culture.[3]
