comment q-Virasoro and q-Heisenberg algebras
In particular, there seems to be no reference to $s_{n+m}$ in the commutator of $\{s_n,s_m\}$.

comment q-Virasoro and q-Heisenberg algebras
Thanks - the second reference is useful. Is there a more symmetric formalism for the deformed virasoro in this reference? It would be easier to see how it relates to other possible definitions.

comment Hopf Galois extensions and conditional expectations for C* algebras
That looks right! Is there a proof of the slice map result in the literature which is really explicit? Alternatively I guess that it is constructing the inner product space for the slice map in the KSGNS theorem, and checking that it really is positive...

Thanks! That solves the problem. Now maybe I shall make a comment on the approximate identity stuff...
