Gelfand-Fuchs cohomology of invariant formal vector fields
arXiv:math/0607582
Abstract
Let $Î$ be a finite group acting linearly on a vector space $V$. We compute the Lie algebra cohomology of the Lie algebra of $Î$-invariant formal vector fields on $V$. We use this computation to define characteristic classes for foliations on orbifolds.
