"Loop groups and noncommutative geometry" |
Abstract: |
We describe the representation theory of loop groups in
terms of K-theory and noncommutative geometry. This is done by
constructing suitable spectral triples associated with the level l
projective unitary positive-energy representations of any given loop
group LG. The construction is based on certain supersymmetric
conformal field theory models associated with LG. The construction can
be generalized, in the setting of conformal nets, to many other
rational chiral conformal field theory models including coset models
and the moonshine conformal net. (Based on a joint work with Robin
Hillier) |
