Axe Histoire et philosophie des mathématiques

Mathematics and Philosophy, 19th and 20eth Centuries /2011–2012

Phds and students Workgroup

Organization : Sylvain Cabanacq,
Emmylou Haffner,
David Rabouin

On Wednesdays, 10:00 am – 13:00 pm, room Rothko (412B).

This working group aims to build an informal space for PhD students working on 19th and 20th Century, whether they are historians or philosophers, to discuss and work together as well as with researchers, students in mathematics and master students.

No prerequisites are expected from participants. On the contrary, the idea is to share historical knowledge, mathematical skills, philosophical insights and points of view. Our starting points will go from recent papers, discussed together, to mathematical theories (for example, group representation) or more “classical” historical and philosophical writings (Weyl, Lautman, …). This year, the group will be organized in series of sessions united by a theme. A large part of each session will be devoted to questions and discussion.

To current year and archives 2011–

Around Cavaillès’ philosophy
Sylvain Cabanacq and Baptiste Mélès

April 12

 !! exceptionnally Room 267A !!

Nous écouterons un échange entre Karine Chemla et David Rabouin sur l’utilisation des notions de concept et d’objet en histoire des mathématique. Partant d’une tentative de préciser ce que signifie faire une histoire "conceptuelle", nous interrogerons les possibilités d’actuelle(s) identification(s) d’un "concept" du point de vue d’une évolution historique. De là, émergent des questions comme : un concept peut-il avoir une histoire ? Comment caractérise-t-on, alors, les évolutions d’un concept ?

Abstraction in a mathematical context

Working group co-organized by Jean-Pierre MARQUIS, Pr. at the Université de Montréal and visiting researcher at SPHERE, and Jean-Jacques SZCZECINIARZ

Would it be possible to define a form of abstraction that could be specifically mathematical ? On the contrary, is it necessary to consider different kinds of abstraction, according to the mathematical contexts in which such a procedure is used (topology, algebraic geometry, algebra…) or to the theories that allow us to characterize it (category theory, model theory, topos theory…) ?
