Cartan, Lebesgue, de Rham and the analysis situs in the 1920s. Scenes of the Parisian life. (Cartan, Lebesgue, de Rham et l’analysis situs dans les années 1920. Scènes de la vie parisienne.) (French) Zbl 1270.01012

This paper deals with mathematicians (Lebesgue, Cartan, Poincaré, Alexandroff, Hopf, “Bourbaki” (as seen through the eyes of G. de Rham)) and their mathematics. De Rham wrote a survey of these important days and work in Paris in the 1920s, on topology, domain invariance, open sets, work of Brouwer, Blumenthal, and many others, the “Seminaire Hadamard”, etc. The whole paper is written like the journey of de Rham through Paris meeting the corresponding persons and their mathematics. A highly original endeavour! So, read the article. An important source is G. de Rham’s paper [“Quelques souvenirs des années 1925–1950”, Cah. Semin. Hist. Math. 1980, No. 1, 19–36 (1980; Zbl 0449.01003)]; the paper under review might be considered as a work-out of that paper, with up-to-date material added. It makes everything highly readable.
