Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

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:

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.
