A generalization of real characters on a group
@YCor, yes initially $G$ and $A$ both were algebras. I reformulated this for the case when $G$ is a group.

Yemon, I think you meant $A(G)\subseteq C_0(G)$.

Ah, I see! No, I meant the usual set of zeroes: $\text{Ker}f=\{x:\ f(x)=0\}$. Yemon, where is this written, about "iff $G$ is amenable"?

Yemon, thank you, yes, I mean the usual kernel. Actually, I don't know, in which other sense it can be understood. Can you give a reference?

When is the induced representation factored through the initial one?
My $H$ is normal. Ben, I need a reference. I must refer to a textbook or to a paper in my text.

Ben, can this be true when $H$ is normal?

I tried to input a diagram, but they seem to do not work here. Is it possible to use diagrams in MO?

Is the ideal of functions vanishing at a set complementable in $C(X)$?
@NarutakaOZAWA, could you, please, give the reference?

Yes, that's unexpected. Thank you, Bill.

But $\beta{\mathbb N}\setminus{\mathbb N}$ is not closed in $\beta{\mathbb N}$.
