There's a huge amount of stuff here! — including notes from more elementary classes that I've taught. If you're interested in LaTeXing any of these notes, let me know. We've already done this with some of the '00-'01 and '06-'07 notes.

- Fall 2000 -
introduction to spin networks and the Lagrangian approach to
gauge theories and gravity. Includes another appearance
of Oz and the Wizard!
- Winter 2001 -
continuation of the Fall 2000 session, covering topological
quantum field theories and quantum electromagnetism in 2d spacetime.
Also, still more tales featuring Oz and the Wizard!
- Spring 2001 -
continuation of the Winter 2001 session,
covering the representation theory of quantum SU(2) and its
application to a 3d topological quantum field theory called
the Turaev-Viro model.
- Fall 2001 - continuation of
the Spring 2001 session, covering the basics of loop quantum gravity.
- Winter 2002 - beginning of a
course on categorified gauge theory. An introduction to
n-categories, with a special emphasis on 2-groups and their
application to categorified electromagnetism, also known as
2-form electromagnetism.
- Spring 2002 - continuation
of the course on categorified gauge theory. Groups and 2-groups,
bundles and 2-bundles!
- Fall 2002 -
introduction to diagrammatic methods in
group representation theory, leading up to the theory of
Feynman diagrams.
- Winter 2003 - no seminar: I was on sabbatical.
- Spring 2003 - a course on
Clifford algebras, spinors, the Dirac equation, and algebraic
patterns in the Standard Model of particle physics, leading up
to the SU(5) grand unified theory.
- Fall 2003 -
beginning of a course on quantization
and categorification, which explains how Feynman diagrams and
a wealth of other combinatorics fall out as a natural consequence
of categorifying the harmonic oscillator.
- Winter 2004 -
continuation of the course on quantization
and categorification. Lots of fun combinatorics: counting
things with generating functions!
- Spring 2004 -
conclusion of the course on quantization
and categorification. Stuff types, stuff operators
and categorified Feynman diagrams.
- Fall 2004 -
beginning of a course on gauge theory and
topology, starting with a history of n-categorical
physics and moving on to the construction of 2d
topological quantum field theories.
- Winter 2005 -
continuation of the course on gauge theory and
topology. 3d topological quantum
field theories, Dijkgraaf-Witten models and group
cohomology!
- Spring 2005 -
conclusion of the course on gauge theory and
topology.
- Fall 2005 - point particles in 3d quantum gravity,
strings in 4d quantum gravity.
This material will find its way into Jeffrey Morton
and Derek Wise's thesis, so we're keeping it secret for now...
but you can see some
here!
- Winter 2006 - point particles in 3d quantum gravity,
strings in 4d quantum gravity, continued.
- Spring 2006 - no seminar: I was on sabbatical.
- Fall 2006 - the seminar
this quarter covers two subjects:
quantization
and cohomology, and
classical versus
quantum computation. Now with blog entries where you can
ask questions!
- Winter 2007 - continuation
of the courses on
quantization
and cohomology and
classical versus
quantum computation.
- Spring 2007 - continuation
of the courses on
quantization
and cohomology and
cohomology and
computation.
- Fall 2007 - beginning of
of a seminar on geometric representation theory, taught by
John Baez and James Dolan. With videos of the lectures.
- Winter 2008 - continuation of
the seminar on geometric representation theory. With videos.
- Spring 2008 - no seminar: I didn't teach this quarter.
- Fall 2008 - a course on Lie theory through examples.
