comment Deformation of the covariant Laplacian
I was actually hopping for equality as subspaces of 2-forms but same dimension should be enough for my purposes.

comment Principal orbits for hamiltonian actions
$(\tilde{H})$ should be the smallest orbit type for $M$ whose orbit type subset $M_{(\tilde{H})}$ has non-empty intersection with $\mu^{-1}(0)$.
