Biography
editTannaka was born in Matsuyama, Ehime Prefecture on December 27, 1908.[1][2][3] After receiving a Bachelor of Science in mathematics from Tohoku Imperial University in 1932, he was appointed a lecturer in the university in 1934 and received a Doctor of Science degree from the university in 1941.[1][3] He was promoted to assistant professor in 1942 and full professor in 1945.[1][2][3] Tannaka was a member at the Institute for Advanced Study from September 1955 to April 1957.[1][3][4] Tannaka retired from Tohoku University in 1972, after which he served as a full professor at Tohoku Gakuin University until 1981.[1][3]
Tannaka was an editor of the Tohoku Mathematical Journal and a member of the board of directors of the Mathematical Society of Japan.[1] Tannaka was also in charge of the "Mathematics Chat" article series in the monthly Mathematics for Universities magazine from 1960 onwards.[5]
Research
editTannaka is known for developing the theory of Tannaka–Krein duality, which generalizes Pontryagin duality to noncommutative compact groups and led to the development of Tannakian formalism.[1][2][6][7]
Awards
editTannaka was a recipient of the Order of the Rising Sun (3rd Class) in 1980.[3]
