Note that we have for the commutator $[\Psi^0, \Psi^0] \subset \Psi^{-1}$ and this inclusion passes of course to the completions. Now $\overline{\Psi^{-1}}$ are exactly all the compact operators $\mathfrak{K}$ since $M$ is compact. So the quotient $\overline{\Psi^0} / \mathfrak{K}$ is abelian, whereas $D^\ast(M) / \mathfrak{K}$ should not be abelian. | |
