 Groupoids and Stacks in Physics and Geometry

From January 8th to April 6th of 2007, the Institut Henri Poincaré
will be running a program on:
   
      Groupoids and Stacks
      in Physics and Geometry

The program on Groupoids and Stacks in Physics and Geometry will feature 
the following workshops:

    *  Higher structures in geometry and physics
      (Jan 15-Jan 19)
      Organizers: Alberto Cattaneo and Ping Xu
Conference in honor of Murray Gerstenhaber's 80th and Jim Stasheff's 70th 
birthdays

    *
      Quantum cohomology of stacks and string theory
      (Feb 12-Feb 16)
      Organizers: Kai Behrend, Barbara Fantechi and Andrew Kresch

    *
      Groupoids in operator algebras and noncommutative geometry
      (Feb 26-Mar 2)
      Organizers: Jean Renault and Jean-Louis Tu

There will also be a number of long courses, including: 

      Kai Behrend and Andrew Kresch,
      Introduction to stacks   


      Lawrence Breen, Categorical Structures and cohomology   


      Jean-Louis Tu, Operator Algebras, K-theory and groupoids
      (abstract)(résumé)  


      Ping Xu, Lie groupoids and Poisson geometry
