Chiral equivariant cohomology II
This is the second in a series of papers on a new equivariant cohomology that takes values in a vertex algebra. In an earlier paper, the first two authors gave a construction of the cohomology functor on the category of $O({\mathfrak {s}}{\mathfrak {g}})$ algebras. The new cohomology theory can be …
