Title: Creation and 40 years evolution of a Journal Dates: 1957-2000 Creation and 40 years evolution of a journal: In the early fifties, Charles Ehresmann had organized a Topology Seminar in Strasbourg, the proceedings of which were published in 3 volumes, under the title: Colloque de Topologie de Strasbourg ". Hence Charles' 1957-58 Seminar was published under the title: ", Vol. I. rd cycle" thesis (on infinite-dimensional polyhedrons), in this volume, and not only the part I had exposed in his seminar. Thus, to have more freedom, we thought of creating an independent publication, not only devoted to the proceedings of the Seminar. The fortuitous meeting of an unused 'Varityper' machine allowed the realization of this project. Until 1966, volumes appeared without strict periodicity (about one volume per annum) and the initial title changed little by little to become in 1966: In 1967 the " Cahiers " were converted into a formal quarterly journal (with no more links with the Seminar), and their current presentation was adopted. From 1967 to 1972, they were published by the Editions Dunod. But a merger of Dunod in 1972 raised problems, and we decided to publish them ourselves, in Paris until 1975, then in Amiens. In Paris, most of the composition of the texts was carried out by secretaries made available for this journal by the "Centre National de la Recherche Scientifique". But when we moved to Amiens at the end of 1975, we had to give up this material aid, whose maintenance was subordinated to conditions unacceptable for us.

Slight corrections have been made, in particular references to Charles' works have been simplified, just indicating in which Part of the "Oeuvres" the papers are reprinted. CHARLES EHRESMANN I have been deeply moved by your idea of dedicating this meeting to my husband. Please excuse me if this talk is somewhat informal, and if my english (which has never been very good) is particularly awful. But my husband died only one month ago, after a year long illness during which he needed incessant care. In any case, it would not have been possible for me to speak objectively about Charles, since we have been so closely related for 22 years. Hence this talk will be mixing Mathematics and more personal recollections; but this is not too inadequate in a Category meeting, our life having been completely devoted to Mathematics, and more precisely to Category Theory and its Applications. Even when he was very ill, Charles often repeated that he wanted to do mathematics; he still said it during the two days of wakefulness which preceded his death. § l. His liking of Travels

Forward Citations Abstract: We show that the Manin triple characterization of Lie bialgebras in terms of the Drinfel'd double may be extended to arbitrary Poisson manifolds and indeed Lie bialgebroids by using double cotangent bundles, rather than the direct sum structures (Courant algebroids) utilized for similar purposes by Liu, Weinstein and Xu. This is achieved in terms of an abstract notion of double Lie algebroid (where double is now used in the Ehresmann sense) which unifies many iterated constructions in differential geometry.

40. Times Obituary He wrote his doctoral thesis in algebraic topology under Henri Cartan in 1951,and then, inspired by charles ehresmann, moved in a more geometric direction. http://www.aam314.vzz.net/Thom.html

Rene Thom Creator of 'catastrophe theory' whose mathematical ventures into higher dimensions won him the Fields Medal Rene Thom, French mathematician, Fields Medallist, philosopher, and the creator of catastrophe theory, was born in Montbeliard on September 2, 1923. He died at Bures-sur-Yvette on October 25, 2002, aged 79. Rene Thom was the co-founder (with Hassler Whitney) of the two new mathematical fields of differential topology and singularity theory. During the 1950s he invented the key tools of these fields, created cobordism theory and classified generic singularities of smooth maps. Cobordism is a way of classifying manifolds, the higher dimensional analogues of spheres and other curved surfaces. When one manifold is mapped into another there are points where the first is unavoidably crinkled up, and these points are called singularities. Manifolds and singularities are fundamental to geometry, and to the understanding of all branches of pure and applied mathematics that use equations. For this work Thom was awarded in 1958, at the age of 35, a Fields Medal, the equivalent in mathematics of a Nobel Prize. Three years later he was appointed to a permanent professorship at the newly created Institut des Hautes Etudes Scientifiques at Bures-sur-Yvette near Paris, where he remained for the rest of his life.
