My C*-algebra notes (from the Fall 2015 course) are now on *AMS Open Math Notes*. You can find them here.

I am putting the notes from my K-theory course online as they are available. You can find them here.

I am starting with a purely algebraic development, as in the first few chapters of Milnor, but will soon dramatically change gear and talk about C*-algebras.

We had the interesting surprise of having a TV reporter in our class the other day. You can view his report/interview here.

I wonder if you know about the AMS *Open Math Notes* project? I only just heard of it, but I feel very positive about any projects that make mathematical content more freely available. Here is the link to the AMS page about the project:

As my students know, I’ve made a habit over the years of putting together TeXed notes for the courses I deliver – especially graduate courses – and now I have quite a number of them. With some pressure on my time (read: cancer) there is no way that I could bring all of these to formal publication, even if that was the right route for them. But as “MathNotes” I can see that they might be helpful. So I’m going to start submitting them, perhaps after light revision, to the AMS site. I made a start today by posting my notes from the Penn State complex analysis (graduate) course, which I’ve delivered three or four times, taking a slightly different tack each time. Based on what I learn from that, I have a good queue of other notes to submit as well. This is actually quite exciting for me.

*Updated, December 20th*: The notes have now appeared on the OpenMathNotes site, and may be found here.

In further exciting (to me) AMS news, my *Winding Around* made it to their 2016 bestseller list! Because of this, the AMS is offering a special discount for orders placed between now and the end of January…

I hope to upload further packages of notes in the new year! Best wishes to all!

Here is the follow-up lecture (second of two) on coarse index theory. I tried to bear in mind that the conferees in Germany had heard quite a few presumably much more detailed presentations in between by lectures 1 and 2, so I attempted to give a fairly “big picture” overview. I had prepared to talk about several examples that I didn’t have time to discuss, so you will find some slides at the end of the presentation below that were not talked about in the video.

Here’s the video of Lecture 2:

And here is the link to the corresponding slides. Hope you find the presentation helpful and enjoyable!

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.
