Minoru Tomita

from Wikipedia, the free encyclopedia

Minoru Tomita ( Japanese 冨 田 稔 , Tomita Minoru ; born February 6, 1924 in Japan ; † October 9, 2015 ) is a Japanese mathematician who made significant contributions to the theory of operator algebras.

Tomita became deaf when she was two years old. He studied at Kyushu University with the degree in 1952. He completed his habilitation at Osaka University and taught at Okayama University from 1954 as an assistant professor and from 1965 as a professor. In 1966 he became a professor at Kyushu University and in 1985 at Fukuoka University .

Tomita and Masamichi Takesaki developed the Tomita-Takesaki theory of the modular automorphisms of Von Neumann algebras . He published very little. The Tomita-Takesaki theory developed by Takesaki on the basis of a manuscript by Tomita (and published in 1968) was, however, essential for the progress made in the classification of Von Neumann algebras by Alain Connes ( type III factors ). It also has applications in quantum mechanics .
