Extractions: Shown here is a note written in Emmy Noether's hand, sent to an editor of Mathematische Annalen, and published as a preface to the article, Jacques Herbrand, "Théorie arithmétique des corps de nombres de degré infini," Mathematische Annalen Following is a partial translation, based on that given on page 43 of James W. Brewer and Martha K. Smith, editors, Emmy Noether: A Tribute to Her Life and Work, Marcel Dekker, New York, 1981: Jacques Herbrand, born on the 12th of February, 1908, in Paris, was killed on the 27th of July, 1931, while mountain-climbing in the French Alps. One of the strongest mathematical talents has passed on with him, just during a time of the most intensive work, while he was full of ideas for the future. The last year of his life, which he spent with a Rockefeller scholarship in Germany, brought him into close contact, both scienfically and personally, with a number of German mathematicians . . .

The Church-Turing thesis states in its most common form that every effective computation or algorithm can be carried out by a Turing machine . The thesis, which is now generally assumed to be true, is also known as Church's thesis (named after Alonzo Church ) and Turing's thesis (named after Alan Turing The thesis might be rephrased as saying that the notion of effective or mechanical method in logic and mathematics is captured by Turing machines. It is generally assumed that such methods must satisfy the following requirements: The method consists of a finite set of simple and precise instructions that are described with a finite number of symbols.

En effet, il n'est pas exhaustif, et donne une plus large part aux travaux de son auteur qu'il ne conviendrait à un ouvrage exhaustif il ne faut pas confondre le A et le Z, et l' Alpha et l' Omega . Le titre fait référence à l'organisation du mémoire, qui pour une grande part prend la forme d'un lexique. Cette organisation a trois origines : d'abord, les travaux présentés ici ont été conduits à plusieurs niveaux d'abstraction qui entretiennent des relations de dépendance mutuelle, ensuite, nous avons voulu fournir des éclaircissements sur des concepts et des noms qui sont utilisés parfois rituellement et sans conscience de leur signification, alors qu'ils sont importants pour le domaine étudié, et enfin, le langage de programmation titre, Prolog, est lui même conçu à la croisée de plusieurs théories. L'organisation en lexique permet de rendre également visibles toutes ces dimensions. Les travaux présentés dans ce mémoire ont été conduits à plusieurs niveaux d'abstraction qui interagissent. Cela est conscient et délibéré car pour nous il n'était pas question d'étudier l'implémentation d'une famille de langages de programmation sans connaître leur utilisation. Et inversement, même si l'utilisateur ordinaire n'a pas à connaître l'implémentation, les experts qui la connaissent peuvent promouvoir telle ou telle pratique de programmation. Chaque langage de programmation propose des techniques de programmation particulières dont on veut parfois développer l'usage. Il faut pour cela que l'implémentation ne cause pas de mauvaise surprise à l'utilisateur. Celui-ci aura en retour de nouvelles exigences, qui doivent à leur tour être implémentées, etc. Cette démarche a guidé nos travaux sur

Andler, "Les mathématiques à l'Ecole normale supérieure", Retour haut de page Ce n'est qu'au congrès de Zurich, en 1932, suite à la mort de Fields et à un legs qu'il fit pour la mise en oeuvre de ces médailles, que la proposition fut acceptée. Fields avait précisé dans son legs que, s'il s'agissait de reconnaître un travail déjà effectué, la médaille devait être également un encouragement à réaliser d'autres progrès en mathématiques. C'est ainsi que la coutume s'imposa de décerner la médaille à des mathématiciens "jeunes", c'est-à-dire d'au plus 40 ans. Si Serre a eu directement peu d'élèves, il a eu une influence considérable sur de très nombreux jeunes mathématiciens. Par ses "cours aux carrés", à l'ENS et à l'ENSJF. Et par ses cours au Collège de France, pour les chercheurs plus avancés, qui furent, pendant des lustres, un rendez-vous hebdomadaire important en mathématiques.

Extractions: Next: 8. Computing satisfiability Up: Thoralf Skolem: Pioneer of Previous: 6. Set theory and In Skolem proved the Skolem-Löwenheim theorem by invoking the axiom of choice. This is not too different from Löwenheim's own proof in 1915. Skolem's proof goes for formulas in Skolem normal form. If one assumes that the formulas are satisfiable in a domain D , then by using the axiom of choice we can find a countable subdomain E of D where the formulas are satisfiable. Löwenheim considered only a single formula, and the use of the axiom choice was formulated as a logical principle using some kind of index calculus. We could perhaps formulate it as the principle in higher order logic But his idea was not that different from Skolem's ( ). One problem here is that there is no constructive way of finding the subdomain E from D An important step was made in . There Skolem considered what is now called the term model. By starting with formulas in Skolem normal form one could give names to all individuals needed in the domain. He used the natural numbers as names here. In he started with Skolem functions for the -quantifiers in the Skolem normal form. Then as names he had all terms built up from the Skolem functions starting with a term 0. Then he switched to using natural numbers instead. He used a simple enumeration of the Skolem terms to do that. The point is that Skolem saw the choice between natural numbers and the Skolem terms for names as just a matter of convenience.

Extractions: for contributions to automated deduction Senior scientist William McCune (MCS) will receive the 2000 Herbrand Award for exceptional contributions to the field of automated deduction. The award is given by the Conference on Automated Deduction (CADE) Inc. to honor exceptional contributions to the field. McCune was cited for his outstanding success in answering the Robbins question, which had challenged mathematicians and logicians for six decades, and for his design of the powerful program Otter, which has become a benchmark for automated deduction programs. McCune's contributions to the field also include powerful inference rules and numerous new strategies that have dramatically increased the likelihood of finding a proof.

Extractions: and Its Contributions to Logic ARSAW SCIENTIFIC SOCIETY, whose official name in Latin reads Societas Scientiarum Varsaviensis , was established in Warsaw, 1800, to advance sciences and arts. It is merited for enormous contributions to scientific and cultural development of Poland. For instance, in the twenties of the 19th century the mechanical calculator of Abraham Stern (a Jewish mechanician from a small town in Eastern Poland) was demonstrated by the constructor and discussed at its sessions. In the first half of our century, its merits are most conspicuous in logic and mathematics. The Proceedings of its sessions played a significant role for mathematics owing to prompt publication of results; their first volume, including some Waclaw Sierpinski's results, appeared in 1908. Consequential achievements, e.g., those on definability, were first announced at its sessions, and seminal works were first published by it, as Jacques Herbrand's Recherches sur la Theorie de la Demonstration , 1930, and Alfred Tarski's Pojecie Prawdy (The Concept of Truth in Formalized Languages), 1933.
