at the Institute for Mathematics and its Applications:

http://www.ima.umn.edu/categories/

We'll mainly be trying to compare different definitions of
n-categories, but there will be an afternoon about applications
of n-categories to mathematical physics, especially topological
quantum field theory. Since most of the audience won't be
experts on physics, I'm giving an introductory talk which may be
of interest to some people here too:

http://math.ucr.edu/home/baez/n_{categories}/index.html#spacetime_and_process

It fills in some of the math that I deliberately avoided in my
paper "Quantum Quandaries: a Category-Theoretic Perspective":

Check it out! You can also see transparencies of my two n-category
talks.
