Shigefumi Mori (森 重文 Mori Shigefumi, born February 23, 1951) is a Japanese mathematician, known for his work in algebraic geometry, particularly in relation to the classification of threefolds.
He generalized the classical approach to the classification of algebraic surfaces to the classification of algebraic threefolds. The classical approach used the concept of minimal models of algebraic surfaces. He found that the concept of minimal models can be applied to threefolds as well if we allow some singularities on them.
The extension of Mori’s results to dimensions higher than three is called the Mori program and, as of 2006, is an active area of algebraic geometry.
He was awarded the Fields Medal in 1990 at the International Congress of Mathematicians.
He was visiting professor at Harvard University during 1977–1980, the Institute for Advanced Study in 1981–82, Columbia University 1985–87 and the University of Utah for periods during 1987–89 and again during 1991–92. He has been a professor at Kyoto University since 1990.
He has been elected president of the International Mathematical Union, becoming the first head of the group from East Asia.^{[1]}
