Enrico Bombieri (born 26 November 1940 in Milan, Italy) is a mathematician, known for his work in analytic number theory, algebraic geometry, univalent functions, theory of several complex variables, partial differential equations of minimal surfaces, and the theory of finite groups. He won a Fields Medal in 1974.〔(Proceedings of the International Congress of Mathematicians, 1974 )〕 ==Career== Bombieri published his first mathematical paper in 1957 when he was 16 years old. In 1963 at age 22 he earned his first degree (Laurea) in mathematics from the Università degli Studi di Milano under the supervision of Giovanni Ricci and then studied at Trinity College, Cambridge with Harold Davenport. Bombieri was an assistant professor (1963–1965) and then a full professor (1965–1966) at the Università di Cagliari, at the Università di Pisa in 1966–1974, and then at the Scuola Normale Superiore di Pisa in 1974–1977. From Pisa he emigrated in 1977 to the USA, where he became a professor at the ''School of Mathematics'' at the Institute for Advanced Study in Princeton, New Jersey. In 2011 he became professor emeritus. Bombieri's research in number theory, algebraic geometry, and mathematical analysis have earned him many international prizes — a Fields Medal in 1974 and the Balzan Prize in 1980. In 2010 he received the King Faisal International Prize (jointly with Terence Tao).〔(King Faisal Foundation ), - retrieved 2010-01-11.〕 He was a plenary speaker at the International Congress of Mathematicians in 1974 at Vancouver. He is a member, or foreign member, of several learned academies, including the French Academy of Sciences (elected 1984), the United States National Academy of Sciences (elected 1996), and the Accademia Nazionale dei Lincei (elected 1976).〔(Scheda socio ), from the website of Accademia dei Lincei (elected 1976)〕 In 2002 he was made ''Cavaliere di Gran Croce al Merito della Repubblica Italiana''. The Bombieri–Vinogradov theorem is one of the major applications of the large sieve method. It improves Dirichlet's theorem on prime numbers in arithmetic progressions, by showing that by averaging over the modulus over a range, the mean error is much less than can be proved in a given case. This result can sometimes substitute for the still-unproved generalized Riemann hypothesis. In 1969 Bombieri, De Giorgi, and Giusti solved Bernstein's problem. In 1976, Bombieri developed the technique known as the "asymptotic sieve".〔E. Bombieri, "The asymptotic sieve", ''Mem. Acad. Naz. dei XL'', 1/2 (1976) 243–269.〕 In 1980 he supplied the completion of the proof of the uniqueness of finite groups of Ree type in characteristic 3; at the time of its publication it was one of the missing steps in the classification of finite simple groups.〔 (This paper completed a line of research initiated by the Walter theorem.)〕 Bombieri is also known for his pro bono service on behalf of the mathematics profession, e.g. for serving on external review boards and for peer-reviewing extraordinarily complicated manuscripts (like the paper of Per Enflo on the invariant subspace problem). Bombieri, accomplished also in the arts, explored for wild orchids and other plants as a hobby in the Alps when a young man. 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「Enrico Bombieri」の詳細全文を読む スポンサード リンク
