    • Presentation of the Logic seminar at Paris 1 University

    This seminar is organized at the Philosophy department of Panthéon-Sorbonne University (Paris 1) by members of the pedagogic team in charge of     the Logic Program ("Licence-Maîtrise de Logique"). The intended public is rather broad: specialists of logic (students included) and all those who in their professional practice (in mathematics, philosophy, computer science, A.I., cognitive sciences, linguistics) meet logic.

    This year again, the seminar is centered around the question:

    WHAT IS A LOGIC ?

    Participants are invited to explain (as possible: in french) how, as representatives of the main branches or trends of Logic or of connected topics, they understand that question, and to present the answers they have elaborated from their practice.

    Practical informations about the Logic Seminar

    Seminar sessions take place at the Sorbonne, every second tuesday, at 18h30, at 17 rue de la Sorbonne (5th arrondissement of Paris), in the Philosophy department, stairway C, 1st floor, Salle Cuzin (Or Cavaillès, or Halbwachs).

    Title: FINITE MODEL THEORY
    Abstract :     Classical logic was developed to confront the Infinite, but in computer science applications it is often meaningful to restrict attention to finite structures e.g. databases.
    This phenomenon gave impetus to the development of finite model theory which happens to be quite different from classical model theory; complexity theory is often a useful guide. We survey these developments including a recent twist a la Hegel (thesis, antithesis, synthesis) concerning so-called meta-finite structures.

    Title: LA LOGIQUE DES MATHEMATIQUES CLASSIQUES.

    (Résumé:
    Par logique classique, j'entends non seulement celle du tiers-exclu, mais plus largement: toute la théorie développée pour analyser et fonder logiquement les Mathématiques classiques (= Théorie des nombres, Géometrie, Algèbre, Analyse). L'essentiel de cette Logique classique se répartit en 4 sous-théories: théorie des ensembles, des démonstrations, des modèles et de la définissabilité. L'exposé touchera aux points suivants:
  • 1/ essence, acquis et problèmes fondamentaux de la Logique Classique;
  • 2/ évolutions récentes, notamment cette chose inattendue: la Logique classique s'avère en un sens PLUS appropriée comme fondement pour l'Informatique théorique que pour les Mathématiques classiques (à condition de ne pas restreindre la Logique à la seule théorie des démonstrations).
