We explicitly construct the adjoint operator of coboundary operator and obtain the Hodge decomposition theorem and the Poincare duality for the Lie algebra cohomology of the infinite?dimensional gauge transformation group. We show that the adjoint of the coboundary operator can be identified with the BRST adjoint

The groups that are relevant in the context of gauge theories consist of same in different representations, the structure constants are always the same, an infinitesimal gauge transformation, because we assume U(x) to be differ- entiable as a function of the space-time coordinates. Hence we may write. U(xµ + dxµ)=(I+ ca.
