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

comment allowing `discontinuous functions' into a C* algebra
Very interesting... I shall have to look further into this, thanks for pointing it out.

comment Example of a covariant derivative on a non-projective bundle
Thanks - there is no chance for a locally trivial bundle to do this. But is there any sheaf-like structure (expressed as a module with connection over the algebra of functions) for which it can be done?

comment Identifying a Hopf algebra cohomology theory
OK, I have added more explanation - apologies for that. There is a way to reformulate the complex with no explicit invariants and no algebra structure.

comment Identifying a Hopf algebra cohomology theory
The required action for the van Est spectral sequence is the full tensor product coaction (this is needed to get a non-trivial dependence on the coaction). I see now that my question was ambiguous on this point. If I remember correctly, the sequence without taking the invariants is acyclic - will check.

The product appears implicitly in the coaction on the tensor product. I am checking the reference - thanks!
