Gregori Aleksandrovich Margulis ((ロシア語:Григо́рий Алекса́ндрович Маргу́лис), first name often given as Gregory, Grigori or Grigory; born February 24, 1946) is a Russian mathematician known for his work on lattices in Lie groups, and the introduction of methods from ergodic theory into diophantine approximation. He was awarded a Fields Medal in 1978 and a Wolf Prize in Mathematics in 2005, becoming the seventh mathematician to receive both prizes. In 1991, he joined the faculty of Yale University, where he is currently the Erastus L. DeForest Professor of Mathematics.〔(【引用サイトリンク】title=Yale's Margulis Wins 2005 Wolf Prize for Mathematics )〕 == Short biography == Margulis was born in Moscow, Soviet Union. He received his PhD in 1970 from the Moscow State University, starting research in ergodic theory under the supervision of Yakov Sinai. Early work with David Kazhdan produced the Kazhdan–Margulis theorem, a basic result on discrete groups. His superrigidity theorem from 1975 clarified an area of classical conjectures about the characterisation of arithmetic groups amongst lattices in Lie groups. He was awarded the Fields Medal in 1978, but was not permitted to travel to Helsinki to accept it in person. His position improved, and in 1979 he visited Bonn, and was later able to travel freely, though he still worked in the Institute of Problems of Information Transmission, a research institute rather than a university. In 1991, Margulis accepted a professorial position at Yale University. Margulis was elected a member of the U.S. National Academy of Sciences in 2001.〔(National Academy of Sciences Elections. ) Notices of the American Mathematical Society, vol. 48 (2001), no. 7, p. 722〕 In 2012 he became a fellow of the American Mathematical Society.〔(List of Fellows of the American Mathematical Society ), retrieved 2013-02-02.〕 In 2005, Margulis received the Wolf Prize for his contributions to theory of lattices and applications to ergodic theory, representation theory, number theory, combinatorics, and measure theory. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Grigory Margulis」の詳細全文を読む スポンサード リンク
