Mar 20, 2021 at 23:31 comment added user167952 @JPMcCarthy Thanks for the reference, I'm familiar with this book but I don't quite see how it helps. Anyways, thanks for your time and help.
Mar 20, 2021 at 23:24 comment added JP McCarthy Something along these lines should be in Timmermann. There is a kind of triangle commutative diagram in the chapter about CQGs. I cannot help further right now apologies
Mar 20, 2021 at 23:19 comment added JP McCarthy I'm looking for a reference but it is the $A_0$ that would be isomorphic - you would be showing all these norms are minimal/equal on $A_0$.
Mar 20, 2021 at 23:11 comment added user167952 @JPMcCarthy Thanks for your comment. Do you have an idea how we can show that these completions are isomorphic?
Mar 20, 2021 at 22:41 comment added JP McCarthy I have seen another version again which says start with $A_0$, which has a Haar state, and define a norm $\|f\|_r=\|\pi_h(f)\|$, and the completion of this is another reduced version. I think what you might need is that all these $A_0$ for all these completions are isomorphic and that all these completions are minimal in that $\|\cdot\|_r\leq\|\cdot\|$ for any other norm on $A_0$.

Changed overlines by tildes to avoid confusion with regard to topological closures.
