Everybody knows how insightful are David Ben-Zvi talks (and comments/answers here on mathoverflow). I was trying to watch the LMS 2007 Lecture Series on Geometric Langlands by David, supposedly made available via GRASP Lectures, but the server is down or no longer exists.

Some of the GRASP lectures are available on the iTunes Podcasts of the University of Texas Austin, but unfortunately not these ones.

Does anybody know where else to find them online or did anyone downloaded them back then and could, please, make them available to the community again?

  • $\begingroup$ the web page is mirrored at the Wayback machine, but apparently the mp3 files are not available (I don't have the plugin, so I'm not certain): web.archive.org/web/20150321074051/http://www.ma.utexas.edu/… $\endgroup$ – Carlo Beenakker Nov 1 '17 at 19:35

  • $\begingroup$ @CarloBeenakker Yes, I've tried that before, but at no avail. $\endgroup$ – Carlos Nov 1 '17 at 19:53
  • $\begingroup$ @IgorRivin What do you mean it works for you? Can you watch the videos and/or download the mp3's? $\endgroup$ – Carlos Nov 1 '17 at 19:54
  • $\begingroup$ Why don’t you email DBZ directly? His address is on his papers. Maybe @davidben-zvi will work too. $\endgroup$ – Aaron Bergman Nov 2 '17 at 14:53

The videos from the LMS lectures and all of the GRASP videos are now available again from the links you gave (for download, not streaming). Many apologies for their long hiatus offline and many thanks for your enthusiasm and persistence!! Please do email me for broken links etc., and I will update the site with some more recent materials.

  • $\begingroup$ Hurray! Thank you David for this invaluable source of resources! $\endgroup$ – Carlos Nov 4 '17 at 21:41
