Groupoids and Stacks in Physics and Geometry
Posted by John Baez
From January 8th to April 6th of 2007, the Institut Henri Poincaré will be running a program on:
This will include a workshop on Higher Structures in Geometry and Physics from January 15th to 19th, in honor of Murray Gerstenhaber’s 80th and Jim Stasheff’s 70th birthdays.
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
- Jean-Louis Tu, Operator Algebras, K-theory and groupoids (abstract)(résumé)
-
Ping Xu, Lie groupoids and Poisson geometry
(abstract)
Some support is available for grad students to attend - see the program website.
Re: Groupoids and Stacks in Physics and Geometry
I was invited to teach a long course, but I can’t make it.
So, I hope n-Category Café customers who attend give us a report on what happens! We can start a blog entry about this program, where people can post their accounts of what happened. When the time comes, just email me a reminder.
