Lecture 10/4 at 10.15

The slides for tomorrows lecture (10/4) will hopefully be posted this evening. If you want to prepare for the lecture, you may have a look at the article by Disyatat and repeat section 5 of my lecture note (the model from the first lecture). A slightly revised version is now on the net. There is nothing new in it, just correction of misprints and sloppy formulations. Remember that the lectures are back at 10.15 in the morning.
