Victor Gershevich (Grigorievich) Kac ((ロシア語:Виктор Гершевич (Григорьевич) Кац); born 19 December 1943 in Buguruslan, Russia, USSR) is a Soviet and American mathematician at MIT, known for his work in representation theory. He discovered Kac–Moody algebras, and used the Weyl–Kac character formula for them to reprove the Macdonald identities. He classified the finite-dimensional simple Lie superalgebras, and found the Kac determinant formula for the Virasoro algebra. Kac studied mathematics at Moscow State University, receiving his M.S. in 1965 and his Ph.D. in 1968. From 1968 to 1976, he held a teaching position at the Moscow Institute of Electronic Machine Building. He left the Soviet Union in 1977, becoming an associate professor of mathematics at MIT. In 1981, he was promoted to full professor. Kac received a Sloan Fellowship in 1981 and a Guggenheim Fellowship in 1986 and the medal of the College de France (1981). He received the Wigner Medal(1996)"in recognition of work on affine Lie algebras that has had wide influence in theoretical physics". In 1978 he was an Invited Speaker (''Highest weight representations of infinite dimensional Lie algebras'') at the ICM in Helsinki, In 1988 a plenary speaker at the AMS centennial conference. In 2002 he gave a plenary lecture (''Classification of Supersymmetries'') at the ICM in Beijing. He is a Fellow of the American Mathematical Society.,〔(List of Fellows of the American Mathematical Society ), retrieved 2013-01-27.〕 a Honorary member of the Moscow Mathematical Society, Fellow of the American Academy of Arts and Sciences and a Member of the National Academy of Sciences. The research of Victor Kac primarily concerns representation theory and mathematical physics. His work has been very influential in mathematics and physics and instrumental in the development of quantum field theory, string theory and the theory of integrable systems. Kac published 5 books and over 200 articles in mathematics and physics journals and is listed as an ISI highly cited researcher. Victor Kac was awarded the 2015 AMS Leroy P. Steele Prize for Lifetime Achievement.〔(2015 AMS Steele Prizes )〕 His brother Boris Katz is a principal research scientist at MIT. ==Bibliography== * * * 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「Victor Kac」の詳細全文を読む スポンサード リンク
