Product-type classes for vertex algebra cohomology of foliations on complex curves
Abstract
We define a product of pairs of double complex spaces Cnm(V, W, F) for gradig-restricted vertex algebra cohomology of codimension one foliation on a complex curve. We introduce a vertex algebra counterpart of the classical %product-type cohomological class using the orthogonality conditions on elements of double complex spaces with respect to the product we introduced.
