Semiinfinite cohomology of Lie-* algebras

Sergey Arkhipov

We construct a geometric version of BRST cohomology complex of a chiral module over a Lie-* algebra using the language of differential graded Lie algebroids in the category of D-mo…

Semiinfinite cohomology of Tate Lie algebras

Sergey Arkhipov

In this note we give a definition of semiinfinite cohomology for Tate Lie algebras using the language of Differential Graded Lie algebroids with Curvature (CDG Lie algebroids).
