The representation-category equivalence for loop group nets
The representation-category equivalence for loop group nets
Let be the compact, simply connected Lie group and the level appearing in the representation categories. Let be the category of representations of the conformal net, let be the category of finite-dimensional vector spaces, and let be the category of Hilbert spaces and bounded linear maps. Write for the category of finite direct sums of irreducible level- integrable positive-energy representations of the affine Lie algebra . The representation-category equivalence conjecture. There is a natural equivalence of categories
This is intended to identify all representations of the conformal net with Hilbert-space completions of finite sums of irreducible affine Lie algebra representations, excluding representations that are not direct sums of irreducibles. Equivalently, via the comparison functor to loop-group representations, it asserts that every level- positive-energy representation is locally normal.
