Semiinfinite cohomology of W algebras

We generalize some of the standard homological techniques to \cW-algebras, and compute the semi-infinite cohomology of the \cW_3 algebra on a variety of modules. These computations provide physical states in \cW_3 gravity coupled to \cW_3 minimal models and to two free scalar fields.

algebra: W(3)
algebra: representation
cohomology
field theory: conformal
string model
phase space
