Gelfand-Fuchs cohomology of invariant formal vector fields
Ilya Shapiro, Xiang Tang
Abstract
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 computation to define characteristic classes for foliations on orbifolds.
