Abstract
Conformal blocks for the Wess–Zumino–Witten model can be constructed out of (co)invariants for affine-Lie-algebra modules.
In the standard setup the result is a vector bundle over the space of configurations of points on the Riemann sphere, equipped with a flat connection: the Knizhnik–Zamolodchikov connection (KZ), encoding the differential equations satisfied by correlation functions.
