Topological Field Theory and Geometric Langlands: notes and audio and video from a lecture series at the KITP Santa Barbara workshop on Geometric Langlands and Gauge Theory, July 2009.

Introduction to Geometric Langlands, notes from lecture at the Vienna workshop on Geometric Langlands and Physics, January 2007.

Lectures from the Gottingen Winterschule on Geometric Langlands: Geometric function theory, Geometric Langlands and Topological Field Theory and Geometric Langlands and Real Groups.

A three-part introduction to the geometric Langlands program I gave in 2002 is available on streaming video courtesy of MSRI: Geometric Class Field Theory, Quantization of Hitchin's Hamiltonians, and Factorization.

The February 2005 Talbot workshop (for which I was the plenary speaker) provided an intense "Geometric Langlands retreat" for graduate students. There are notes available as one huge file or as individual pages courtesy of Megumi Harada.

What's the deal with Geometric Langlands?: lecture notes taken by Parker Lowrey for a talk I gave at the Algebraic Geometry Boot Camp, a warmup workshop for graduate students attending the 2005 AMS Summer Institute in Algebraic Geometry, Seattle.

The Geometric Langlands Program, audio for a lecture I gave at the Workshop on Forms of Homotopy Theory: Elliptic Cohomology and Loop Spaces at the Fields Institute in Toronto, 2004.

Here are links to the ICM addresses of Bezrukavnikov and Braverman, closely related to geometric Langlands. Gerard Laumon's Bourbaki talk Travaux de Frenkel, Gaitsgory et Vilonen sur la correspondance de Drinfeld-Langlands surveys the proof of the geometric Langlands conjecture for GL_n.

Edward Frenkel (arxiv search) has written several excellent survey articles on aspects of the geometric Langlands program:

- Recent Advances in the Langlands Program. Bull Amer. Math. Soc. 41 (2004) 151-184. Journal link, math.AG/0303074
- Affine Algebras, Langlands Duality and Bethe Ansatz. XIth International Congress of Mathematical Physics (Paris 1994) 606--642. International Press, Cambridge MA 1995. math.QA/9506003.

- Gaudin model and opers
- Affine Kac-Moody algebras, integrable systems and their deformations
- Lectures on Wakimoto modules, opers and the center at the critical level
- Free field realizations in representation theory and conformal field theory (ICM address)

Here are files of two works by A. Beilinson and V. Drinfeld (posted with the authors' permission). (Most of these are g-zipped postscript - to read these, apply "gunzip (filename)" to obtain a postscript file.) Chiral Algebras (version: 9/00 --- far from the published final version), and Quantization of Hitchin's Integrable System and Hecke Eigensheaves (uncompressed pdf version), Quantization of Hitchin's Integrable System and Hecke Eigensheaves (gzipped ps version) (version: 2/00) These files are quite large - to get 100 pages at a time, download the following: Hitchin Pages 1-100, Hitchin Pages 101-200, Hitchin Pages 201-300, and Hitchin Pages 301-384. Chiral Pages 1-100, Chiral Pages 101-200, and Chiral Pages 201-273.

David Goss kindly provided the backstory for this mysterious appearance of Drinfeld modules: "I grew up in the Detroit area with a number of great people who have gone on to great things; some of them in showbiz. My dear friend Michael Loceff is one such. He and I studied math together at Michigan. After a few years Michael lost interest in his studies and went on to other things. He teaches computer science over the web at Foothill college using software he wrote. Michael's cousin is Joel Surnow and Michael started to write with Joel on "La femme Nikita" and now Michael is an executive producer and write for 24. So you can imagine where the mention of Drinfeld modules arose! ... Finally, Michael likes to use names of people he grew up with in the show. In one episode at the beginning of season 2 or 3 (I never saw it) there is a dead drug dealer named "David Goss" and Jack Bauer goes around asking people if they knew this drug dealer.... One has to have a sense of humor."
