Rimhak Ree

Rimhak Ree, (also cited In - hak Ree, born December 18, 1922 in Hamhung, † 9 February 2005 in Vancouver ) was a Korean- Canadian mathematician, especially focused on group theory, especially with finite groups.

Ree went in Hamhung in North Korea today to school and studied physics from 1939 to the Keijo Imperial University, founded in 1924 a Japanese university in Seoul. Korea was then under Japanese rule. In 1944 he received his degree in physics (mathematics degrees at that time were not possible) and then worked in an aircraft factory in Shenyang (then Fengtian ) in China, which was at that time under Japanese rule. In 1945 he returned to the Japanese defeat to Korea and taught mathematics from 1947 at the Seoul National University, which had emerged from the Keijo University. In 1949 he also published his first mathematical work in the Bulletin of the American Mathematical Society - 1947 he solved a problem about power series, the Max Zorn had put in a previous issue, and sent the solution to anger. During the Korean War, he fled to the south of the country and went to Canada in 1953, where in 1955 he became a PhD from the University of British Columbia with Stephen Jennings ( Witt Algebras ). As a post - graduate student, he was a lecturer at Montana State University and then again at Jennings at the University of British Columbia. 1959/60 he attended Columbia University. In 1961 he was Assistant Professor at the University of British Columbia. 1961/62 he was at Yale University.

1960 and 1961, he was later named after him finite groups of Lie type ( Ree groups). He was given excited by the analysis of the fundamental work of Claude Chevalley in 1955, which also led to his first release on finite groups in 1957, and by Michio Suzuki in 1960 newly discovered family of finite groups of Lie type. Ree 's groups were the last missing families of finite groups of Lie type.

He was married twice and had two daughters from his first and three sons from his second marriage.

In 1964 he became a Fellow of the Royal Society of Canada.
