BRST Reduction of the chiral Hecke Algebra

I. Shapiro

We explore the relationship between de Rham and Lie algebra cohomologies in the finite dimensional and affine settings. As an application, we describe the BRST reduction of the chi…

Gelfand-Fuchs cohomology of invariant formal vector fields

Ilya Shapiro, Xiang Tang

Let $Γ$ be a finite group acting linearly on a vector space $V$ . We compute the Lie algebra cohomology of the Lie algebra of $Γ$ -invariant formal vector fields on $V$ . We use this…
