Semiinfinite cohomology in conformal field theory and 2-d gravity

We discuss various techniques for computing the semi-infinite cohomology of highest weight modules which arise in the BRST quantization of two dimensional field theories. In particular, we concentrate on two such theories -- the

G/H

coset models and

2d

gravity coupled to

c\leq 1

conformal matter. (to appear in the proceedings of the XXV Karpacz Winter School)
