On Some Mathematics in Garrett Lisi's "E8 Theory of Everything"

Abstract: A physicist, Garrett Lisi, has published a highly controversial, but fascinating, paper purporting to go beyond the Standard Model in that it unifies all 4 forces of nature by using as gauge group the exceptional Lie group E8. My talk, strictly mathematical, will be about an elaboration of the mathematics of E8 which Lisi relies on to construct his theory.

This talk was given as a colloquium at U.C. Riverside. Earlier on the same day John Baez gave an elementary introduction to E8. You can also can see this talk as streaming video or downloadable video.

Here is Lisi's paper:

and here is some criticism of it: Some other relevant papers include:
