寄り道ですが
１）グロタンディクの分解原理は、別にリンクあり（下記）
　これは、1957 "American Journal of Mathematics"で、彼がアメリカ滞在時の仕事なのだろう
２）かれは、1955〜1957年にアメリカにいて、"Tôhoku paper"を書いた。フランス国籍がなく仏ではアカデミックポストは困難だった
　”In 1957 he was invited to visit Harvard by Oscar Zariski”とあるが、he refused to sign a pledge promising not to work to overthrow the United States government（機械訳：アメリカ合衆国政府を転覆させるために働かないと約束する誓約書への署名を彼が拒否した）
　のでダメになったという
３）1958 IHÉSへ。IHÉSは、無国籍のグロタンディクのために作られたという

Birkhoff–Grothendieck theorem
In mathematics, the Birkhoff–Grothendieck theorem classifies holomorphic vector bundles over the complex projective line. In particular every holomorphic vector bundle over
CP^1 is a direct sum of holomorphic line bundles. The theorem was proved by Alexander Grothendieck (1957, Theorem 2.1),[1] and is more or less equivalent to Birkhoff factorization introduced by George David Birkhoff (1909).[2]

Alexander Grothendieck
Studies and contact with research mathematics
In Nancy, he wrote his dissertation under those two professors on functional analysis, from 1950 to 1953.[29] At this time he was a leading expert in the theory of topological vector spaces.[30] In 1953 he moved to the University of São Paulo in Brazil, where he immigrated by means of a Nansen passport, given that he had refused to take French nationality (as that would have entailed military service against his convictions). He stayed in São Paulo (apart from a lengthy visit in France from October 1953 - March 1954) until the end of 1954. His published work from the time spent in Brazil is still in the theory of topological vector spaces; it is there that he completed his last major work on that topic (on "metric" theory of Banach spaces).
