Roger Godement (born 1921) is a French mathematician, known for his work in functional analysis, and also his expository books.
He started as a student at the École normale supérieure in 1940, where he became a student of Henri Cartan. He started research into harmonic analysis on locally compact abelian groups, finding a number of major results; this work was in parallel but independent of similar investigations in the USSR and Japan. Work on the abstract theory of spherical functions published in 1952 proved very influential in subsequent work, particularly that of Harish-Chandra. The isolation of the concept of square-integrable representation is attributed to him. The Godement compactness criterion in the theory of arithmetic groups was a conjecture of his. He later worked with Jacquet on the zeta function of a simple algebra.
He was an active member of the Bourbaki group in the early 1950s, and subsequently gave a number of significant Bourbaki seminars. He also took part in the Cartan seminar.
His book Topologie Algébrique et Théorie des Faisceaux from 1958 was, as he said, a very unoriginal idea for the time (that is, to write an exposition of sheaf theory); as a non-specialist, he managed to write an enduring classic. It introduced the technical method of flasque resolutions. It has also been credited as the place in which a comonad can first be discerned.
He also wrote texts on Lie groups, abstract algebra and mathematical analysis.

評分從最基礎的數理邏輯和集閤論講起,有點不習慣。但是慢慢覺得講得是極其有美感,可惜例題太少,習題也沒有提示和解答。翻譯是繞不過去的坎,不做過多評論,但是對照英文版,中文版明顯有譯錯的,有些句子讀起來莫名其妙,建議對照英文版。吐槽校對,看瞭30頁,發現6個錯誤,發火...
