Geometric Representation Theory Seminar - Fall 2007

John Baez and James Dolan

This fall, our seminar is tackling geometric representation theory — the marvelous borderland where geometry, groupoid theory and logic merge into a single subject. The seminar is jointly run by John Baez and James Dolan. Besides explaining well-known stuff, we'll report on research we've done with Todd Trimble over the last few years.

For much more on the subject of this seminar, see:

Below you can find videos and handwritten notes of the seminar. As usual, the seminar will meet on Tuesdays and Thursdays, and you can ask questions and read more discussion at the n-Category Café: the classes all have blog entries to go with them, which you can access below.

For more information on the videos and problems you may encounter watching them, see this.

This seminar is continuing into the winter quarter - check it out!

Videos

We're offering the above videos in streaming and/or downloadable form, both as .mov files. Downloading them takes a long time, but you may need to do this, since the streaming videos seem to work well only if you have a good internet connection.

.mov files can best be played using a free program called QuickTime. If you have QuickTime and your web browser has .mov files associated to this program, you should be able to click on the "Streaming Video" links above and watch the videos. An alternate method is to launch the QuickTime player on your computer, click on "File" and then "Open URL", and type in the URLs provided above. This has the advantage that you can easily make the picture bigger.

If you can handle URL's that begin with rtsp, you can instead go the corresponding URL of that form, for example:

rtsp://mainstream.ucr.edu/baez_10_9_stream.mov

This may also have advantages, but at present my computer gags on such URL's, so I don't know.

Errata

If you catch mistakes, let me know and I'll add them to the list of errata. There may also eventually be some LaTeX, encapsulated PostScript and xfig files to download if for some bizarre reason you want them. However, we reserve all rights to this work.
