 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



If you don’t know about groupoids and stacks, or even if you do, try this
overview of the subject.

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

     *
       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

     *
