I gave the first of the two coarse index theory lectures yesterday. The Polycom equipment makes a recording as standard, and I have uploaded it to YouTube. So, you can take a look. Is this an effective way to communicate mathematics? It seemed to me to work pretty well.

I reviewed the basic definitions of the coarse index and then presented the always-elegant example of the partitioned manifold index theorem. It seemed as though the presentation could be followed well enough by the German audience; only the business of asking and answering questions was a bit clunky. Here is a direct link to the slides.

HunThis is cool! I appreciate your posting of it!
