Kunihiko Kodaira - Kunihiko Kodaira

Japanese: 小平邦彦 - こだいらくにひこ

Born: March 16, 1915, Tokyo
[Died] July 26, 1997. Mathematician, Yamanashi, Shirane. Graduated from the Department of Mathematics at the University of Tokyo (1938) and Department of Physics (41). After serving as an assistant professor at the University of Tokyo, he was invited to the Institute for Advanced Study in Princeton, USA (49), and then became a professor at Princeton University. He worked at Harvard University from 1960, and served as a professor at Johns Hopkins University and Stanford University, during which time he was elected a member of the Japan Academy. He returned to Japan in 1967 and became a professor at the University of Tokyo, retiring in 1975. One of his main achievements was treating algebraic varieties using analytical methods and establishing Kodaira's theorem. Kodaira's theorem is an extension of the Riemann-Roch type theorem to the case of multidimensional compact complex varieties, which states that "Hodge varieties can be biholomorphically embedded in an appropriate complex projective space." At the World Congress of Mathematicians in 1954, he became the first Japanese to receive the Fields Medal, known as the Nobel Prize of mathematics, for his contributions to the theory of harmonic integrals. In 1987, he was awarded the Japan Academy Prize and the Order of Culture, and in 1987, the First Class Order of the Sacred Treasure.

数学者。東京大学数学科 (1938) ，同物理学科卒業 (41) 。東京大学助教授を経て，アメリカのプリンストン高級科学研究所へ招かれ (49) ，その後プリンストン大学教授に就任。 1960年からハーバード大学勤務，ジョンズ・ホプキンズ大学教授，スタンフォード大学教授を歴任し，その間，日本学士院会員に選ばれる。 67年に帰国し東京大学教授に就任，75年退官。おもな業績の一つは，代数多様体を解析的方法で取扱い，「小平の定理」を確立したことである。それはリーマン・ロッホ型定理を，多次元のコンパクト複素多様体の場合に拡張したもので，「ホッジ多様体は，適当な複素射影空間に，双正則にはめこむことができる」というものである。 54年度の世界数学者会議において，調和積分論への貢献により，数学のノーベル賞といわれるフィールズ賞を日本人として初めて受賞。 57年に日本学士院賞および文化勲章を，87年に勲一等瑞宝章を受けた。
