Lecture notes

I'm currently preparing a set of lecture notes for the course (starting from Geir Ellingsrud's excellent notes from last year). They can be found here:

Lecture notes - MAT4215.

I'll try to update them regularly as we progress with the course.

Note: I'd be very glad to get some feedback on the notes along the way. In particular, if there is something unclear or could be presented in a better way, please feel free to let me know. Also, I'm sure there are several typos in there, any help in resolving them would be greatly appreciated!
