Ichirō Satake (佐武 一郎, Satake Ichirō) est un mathématicien japonais travaillant sur les groupes algébriques né le 25 septembre 1927. Il a introduit l'isomorphisme de Satake et les diagrammes de Satake. Satake, qui a travaillé aussi bien pour des universités japonaises qu'américaines, est mort d'une insuffisance respiratoire le 10 octobre 2014.

| dbo:abstract | Ichirō Satake (jap. 佐武 一郎, Satake Ichirō; * 1927 in der Präfektur Yamaguchi, Japan; † 10. Oktober 2014 in Tokyo) war ein japanischer Mathematiker. Satake promovierte 1950 an der Universität Tokio. Er war Professor an der University of Chicago und ab etwa 1970 an der University of California, Berkeley. 1958 bis 1960 und 1967 war er am Institute for Advanced Study. Satake arbeitete über algebraische Gruppen und ihre Klassifizierung. 1957 gab er eine Kompaktifizierung des siegelschen oberen Halbraums in mehreren komplexen Dimensionen an. Nach ihm ist die Satake-Kompaktifizierung durch die Wirkung arithmetischer Gruppen definierter symmetrischer Räume benannt. Satake ist am 10. Oktober 2014 an Respiratorischer Insuffizienz verstorben. (de) Ichirō Satake (佐武 一郎, Satake Ichirō) (25 December 1927 – 10 October 2014) was a Japanese mathematician working on algebraic groups who introduced the Satake isomorphism and Satake diagrams. He was considered an iconic figure in the theory of linear algebraic groups and symmetric spaces. Satake was born in Tokyo, Japan in 1927, and received his Ph.D. at the University of Tokyo in 1959 under the supervision of Shokichi Iyanaga. He was a professor at University of California, Berkeley from 1968 to 1983. After retirement he returned to Japan, where he spent time at Tohoku University and Chuo University. He died of respiratory failure on 10 October 2014. Although they are often attributed to William Thurston, Satake was the first to introduce orbifold, which he did in the 1950s under the name of V-manifold. In , he gave the modern definition, along with the basic calculus of smooth functions and differential forms. He demonstrated that the de Rham theorem and Poincaré duality, along with their proofs, carry over to the orbifold setting. In , he demonstrated that the standard tensor calculus of bundles, connections, and curvature also carries over to orbifolds, along with the Chern-Gauss-Bonnet theorem and Shiing-Shen Chern's proof thereof.
