comment Can we expect $\left\||f|^{2}f-|g|^{2}g\right\|\leq C ||f-g||$ in the Banach algebra $A(\mathbb T)$ ?
Although, I must say that the whole $M=2\|f_0\|$ thing is very mysterious...

But that's not what the question asked: $f_0$ is fixed, this gives $M$ and then the OP specifically asks only for $f,g\in B_M$. If it was meant to be uniform, then why both with the $B_M$ condition?

comment Does anybody know if the Fourier algebra of SL(3,Z) has an approximate identity?
What do you mean by "somewhat technical partial converse"? Just Thm 1.11, namely some sort of tensoring against a group with a sufficient rich set of representations?

comment How a unitary corepresentation of a Hopf C*-algebra, deals with the antipode?
Okay, I'm not sure I have much deeper to say than that actually...

comment How a unitary corepresentation of a Hopf C*-algebra, deals with the antipode?
Sure! But why the antipode behaves in this way is perhaps interesting (and, in some sense, forms the basis for the definition of the antipode in more complicated analytic quantum group settings).
