Irregular WNZW conformal blocks

Verma modules for affine Lie algebras define conformal blocks in 2-dimensional CFT, and are related to the quantisation of moduli spaces of logarithmic connections. In this talk we will review this story, and introduce generalised affine-Lie-algebra modules to define irregular versions of conformal blocks: these will be related to the quantisation of moduli spaces of arbitrary irregular meromorphic connections on the sphere.
