BRST cohomology for relaxed highest-weight affine sl2 modules
Evan WIlliams Theatre

The Virasoro algebra and its representation theory is central to the study of Conformal Field Theory. It is known that the highest weight modules of the Virasoro algebra can be obtained from the affine sl2 highest-weight modules as a BRST cohomology. In this talk we will discuss a possible generalisation of this result by considering the BRST cohomology for the relaxed highest-weight affine sl2 modules.
