## Graduate courses

### Trace formula (2009-2010).

I gave a short series of lectures (at graduate student level) about the trace formula. The lectures
were 1200-1315 or so, on Wednesdays, starting 12/05/10, missing 02/06/10
because of the London-Paris Number Theory Seminar, and finishing 23/06/10
when the seminar finishes. Here's what I wrote about it at the time:

Syllabus---my main aim, which might be too optimistic, is to at least say
something about how one can use the trace formula to prove theorems
of Jacquet-Langlands type for automorphic forms on the group GL_2, although
I will restrict to the case of compact quotient when the going gets tough.
Along the way I'll give an introduction to (what little I know about) the
trace formula and do some toy examples; I will also set up some of the theory
of automorphic forms on GL_2 and their relations to modular forms.

References:

1) The book "Automorphic forms on GL(2)" by Jacquet and Langlands, although
I will very much be picking and choosing from this, rather than working
through it.

2) The first 5 or 6 sections of David Whitehouse's notes "An introduction to the trace
formula", which taught me a great deal. There are typos in these notes; I told
David about them a while ago but he never fixed them :-/ Try here (update: link changed to a direct
link to the paper on Whitehouse's site). (BREAKING NEWS: Wed 12th May: Whitehouse tells me that he's updated the
pdf fixing some typos.)

After the course, some natural next places to go are:

3) Gelbart's lectures on the non-compact case at ArXiv here.

4) Michael Harris' introductory article on endoscopy here.

### L-functions (2008-2009).

This was a course run as part of the Bath/Bristol/Imperial/Oxford/Warwick
Taught Course Centre (TCC). The course ran from Oct to Dec 2008. The lectures were of course
in the Access Grid room (on Mondays 1115-1215 and Tuesdays 1400-1500) throughout
the term (13th Oct - 12th Dec 2008).
The syllabus is here.

The current state of the slides for the course is here (rescaled to fit several slides on a page). The date which I last modified the slides is shown at the top of the 1st page of that pdf file.

I can't imagine that in general people would be interested in the actual pdfs of the slides, but they are here. NOTE THAT THIS IS OVER 100 PAGES AND COUNTING! DON'T PRINT THIS OUT! PRINT OUT THE THING FROM THE LINK IN THE ABOVE PARA!

Here's an example sheet! (24/10/08). And here's another one! (14/11/08). And
another! (14/11/08). And
yet another! (09/12/08).
