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.

Mathematical Aspects of String and M-Theory in Cambridge

Posted by Urs Schreiber

The workshop Mathematical Aspects of String and M-theory is currently is taking place in Cambridge, in the context of the program Mathematics and Applications of Branes in String and M-theory.

I am not there (I am at Higher structures along the lower Rhine), but my co-author Hisham Sati is. Hisham is speaking about our upcoming article with Domenico Fiorenza, on the 7-dimensional Chern-Simons QFT of String 2-connections dual to M5-branes. That’s the one I had briefly mentioned in my talk in Göttingen a few weeks back. A nice application of higher cohesive topos theory, I think.

While, judging from the workshop abstracts, this seems the only higher category theory that is explicitly mentioned in Oxford, of course there is secretly higher category theory all over the place in this subject. For instance the two talks on generalized complex geometry are secretly about the geometry of Courant Lie 2-algebroids.

I’ll post more details a little later.
