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.

Copenhagen Meeting on Differential Characters

Posted by Urs Schreiber

Am in Denmark on vacation. And for attending a day or two of the

Copenhagen meeting on differential characters.

Differential characters are one model for what Deligne cohomology and abelian nn-gerbes with connection are other models for: the differential cohomology refinement of the ordinary Eilenberg-MacLane cohomology theory K(,)K(-,\mathbb{Z}).

Myself, I’ll talk about this:

\infty-topos theoretic differential characters and the \infty-Chern-Weil homomorphism on principal \infty-bundles.
