[email protected] 2DIPARTIMENTO DI MATEMATICA DELL’UNIVERSITÀ, TORINO, ITALY. [email protected] Summary: On the occasion of the ICMI centenary, the authors of the present paper built the website “The First Century of the International Commission on Mathematical Instruction (1908-2008). History of ICMI,” which contains information and documents about people, events, and bodies intervening in the first century of this Commission. This website provides an effective instrument for revisiting the history of ICMI and for reflecting on some key moments. In particular, it makes it possible to identify how the key ideas (internationalization, communication, solidarity) that inspired the founding of ICMI were realized, as well as the how the relationship with the community of mathe- maticians changed. In the present paper we walk through the Portrait gallery section of the website, fo- cusing on the presidents of ICMI and their contributions to the evolution of both the Commission’s policies and its methodological approaches to problems, looking at the history of ICMI from the perspective of the people who built it. Moreover, we present some statistical data concerning the life of ICMI (people, countries, meetings, etc.) and also offer flashes of lesser-known aspects that came to light after a reading of the doc- uments housed in ICMI Archives in Helsinki.

Il y partagea les conversations de salle d’´etude du math´ematicien Andr´eWeil et du phy- sicien Yves Rocard, tous de la mˆeme promotion. Se retrouv`erent aussi `a l’ENS les math´ematiciens Henri Cartan, fils d’Elie Cartan, Jean Coulomb (math´ematicien physicien), Paul Dubreil, Ren´ede Possel et le futur phi- losophe des math´ematiques Jean Cavaill`es (de la promotion 1923). Puis Marcel Brelot, Jean Dieudonn´eet Charles Ehresmann entr`erent `al’ENS en 1924, une promotion qui accueillit plusieurs futures c´el´ebrit´esdes sciences et des lettres tels le physicien Louis N´eel, les philosophes Raymond Aron, Georges Canguilhem, Paul Nizan et Jean-Paul Sartre. Delsarte avait quitt´e la rue d’Ulm quand les math´ematiciens Claude Chevalley et Jean Leray travers`erent l’illustre portail en 1926. Plusieurs de ces math´ematiciens nor- maliens form`erent plus tard le noyau originel du groupe Bourbaki.

This article explains the contributions of Claude Chevalley to class field theory. His leading motivation on the subject seemed to be to give an “arithmetic proof” to the theory and to reveal the nature of the outstanding harmony of the Takagi–Artin class field theory, which had been established just at the time he started his research. His main achievements on the subject may have been the first arithmetic proof of the local class field theory without depending on the global theory, arithmetization of the global class field theory, and its generalization and presen- tation for infinite extensions by introducing ideles, which are now a kind of natural language in algebraic number theory. On the one hand, in this article we have attempted to provide rigorous mathematical description. On the other hand, although we have not demonstrated any proof, we have endeavored to show the development of the series of mathematical ideas that produced a variety of important concepts, bore fruit as class field theory, and then moved Chevalley to create his remarkable and influential works. Keywords and phrases: class field theory, idele, C.

    J Fourier Anal Appl (2011) 17: 320–354 DOI 10.1007/s00041-010-9131-8 Interpolation and Sampling: E.T. Whittaker, K. Ogura and Their Followers P.L. Butzer · P.J.S.G. Ferreira · J.R. Higgins · S. Saitoh · G. Schmeisser · R.L. Stens Received: 7 December 2009 / Published online: 13 July 2010 © Springer Science+Business Media, LLC 2010 Abstract The classical sampling theorem has often been attributed to E.T. Whittaker, but this attribution is not strictly valid. One must carefully distinguish, for example, between the concepts of sampling and of interpolation, and we find that Whittaker worked in interpolation theory, not sampling theory. Again, it has been said that K. Ogura was the first to give a properly rigorous proof of the sampling theorem. We find that he only indicated where the method of proof could be found; we identify what is, in all probability, the proof he had in mind. Ogura states his sampling the- In Memory of Gen-ichirô Sunouchi (1911–2008), a Great Mathematician and Human Being Communicated by Hans G. Feichtinger. P.L. Butzer · R.L.

  • Infinitesimal Variations of Hypersurfaces of a Kaehlerian Manifold
    J. Math. Soc. Japan Vol. 29, No. 2, 1977 Infinitesimal variations of hypersurfaces of a Kaehlerian manifold Dedicated to Prof. Shokichi Iyanaga on his seventieth birthday By Kentaro YANG (Received Feb. 10, 1976) (Revised May 27, 1976) § 0. Introduction. B. Y. Chen [1, 2, 3], C. S. Houh [2], S. Tachibana [10] and the present author [3, 9, 10] have recently studied infinitesimal variations of submanif olds of Riemannian and Kaehlerian manifolds. (See also [7].) The main purpose of the present paper is to study infinitesimal variations of hypersurfaces of a Kaehlerian manifold, to obtain variations of structure tensors of the almost contact metric structure induced on the hypersurf aces from the Kaehlerian structure of the ambient manifold and to prove theorems on variations of Sasakian hypersurf aces with f -sectional curvature a2. (For the definition of a Sasakian manifold with f -sectional curvature a2, see § 1.) In § 1 we state some preliminaries on almost contact metric structure in- duced on a hypersurface from the Kaehlerian structure of the ambient mani- fold. In § 2 we consider infinitesimal variation of a hypersurface of a Kaehlerian manifold and obtain variations of structure tensors of almost contact metric structure induced on the hypersurf ace. § 3 is devoted to the study of what the author calls parallel variation and § 4 to that of variation of the second fundamental form of the hypersurface. In the last § 5, we consider variations of a Sasakian hypersurf ace with f sectional curvature a2 and obtain the condition that an infinitesimal variation carries a Sasakian hypersurf ace with f -sectional curvature a2 into a hyper- surface of the same kind.
