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.

Nekrasov Lecture Online I

Posted by urs

A while ago we had talked about (I, II, III) how gerbes of chiral differential operators make an appearance in Berkovits’ formulation of the superstring in terms of a curved βγ-system of pure spinors. As Peter Woit has already noted on his blog, Nikita Nekrasov is currently lecturing on his latest preprint

Nikita Nekrasov
Lectures on curved beta-gamma systems, pure spinors, and anomalies

in Jerusalem, and a quicktime video of his lectures is available online.

I have watched the first two parts, hoping to see some hints concerning open questions like those mentioned here. But no luck so far…
