1899‐1986 Mathematician born in Kobrin, Belarus. While studying mathematics at the University of Rome, his hometown was incorporated into Poland, and in 1939 it was incorporated into the Soviet Union. He moved to the United States in 1927, became a naturalized citizen in 1936, and taught at Johns Hopkins University until 1945. He spent most of his time thereafter at Harvard University. He retired in 1969, but spent a long time there after retirement for research. His field of research is algebraic geometry, and he is known for constructing new theories using commutative algebra theory, achieving various results in the theory of algebraic surfaces, establishing the theory of rational correspondences in general dimensions, and proving the existence of projective varieties that have the same rational function field as a given three-dimensional algebraic variety and have no singular points.

1899‐1986 白ロシアのコブリンで生まれた数学者。ローマ大学で数学を学んでいる間に故郷はポーランドに編入,1939年にはソ連に編入されている。1927年にアメリカに渡り,36年帰化,ジョンズ・ホプキンズ大学で45年までの間教鞭をとった。その後の大部分の期間はハーバード大学で過ごしている。69年には退職したが,退職後に研究のためハーバード大学へ通った期間も長い。研究の分野は代数幾何学であり,可換環論を利用した新しい理論構成を行い,代数曲面の理論に多様な成果をあげるとともに,一般次元の有理対応の理論を築き,与えられた三次元代数多様体と同一の有理関数体をもつような射影多様体で特異点をもたないものの存在を示したことなどで有名である。 出典 株式会社平凡社世界大百科事典 第2版について 情報 |
