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.

Slides for Freed’s Andrejewski Lecture

Posted by Urs Schreiber

As Bruce Bartlett kindly pointed out to me, the slides of (the first part of) Dan Freed’s Anrejewski Lecture in Leipzig last spring are available on his website:

Dan Freed
Twisted K-Theory and the Verlinde Ring

On these introductory slides, Freed recalls the Freed-Hopkins-Teleman theorem, mentions how fusion of loop group representations can be understood from the fusion of strings, how quantum field theory is about representations of cobordism categories and how quantum evolution by means of the path integral can be understood from pull-push through correspondences of configuration spaces.
