Dear colleagues, Here is a colloquium on logic, categories and formal semantics. We have 8 places left (if there are extra participants, they possibly will have to take care of their lunches). Registration is free, but the program below is worth a visit to Bordeaux. Best regards, -- Christian Retoré http://www.labri.fr/perso/retore LOGIQUE, CATEGORIES, SEMANTIQUE / LOGIC, CATEGORIES, SEMANTICS international colloquium organised by Jean Gillibert & Christian Retoré (IMB, INRIA, LABRI) under the auspices of the French Mathematical Society (SMF) http://www.labri.fr/perso/retore/LCS/index.html 12 AND 13 NOVEMBRE 2010 Salle de conférences Institut de Mathématiques de Bordeaux Bât.

Topic of the workshop The relationship between logic and category theory goes back to the seventies, with the important connection between intuitionistic logic, sheaves and topoi (1) but it extended into other directions, in particular the proof as morphisms semantics (2), and we also include the study of proof normalisation (3). Ideally, the workshop will consider the three levels of foundations , according to the terminology of Jean-Yves Girard, as well as their mutual relationships. These structures provide models of computation but also models of meaning organisation des lexemes, phrases, sentences, discourses and dialogues: we do not exclude the first application, but we shall privilege the linguistic application which is quite new, although Joachim Lambek suggested to do so more than twenty years ago. http://www.labri.fr/perso/retore/LCS/index.html
