Marc, could you, please, advise reading about the case of $C^\infty$?

comment Can a continuous function on a compact group $G$ be interpreted as the sum in $C(G)$ of its Fourier series?
Ah, OK, thank you, I did it.

Yes, I think that there must (probably) be a tricky summation method like the Fejér one.

I gave the link to MSE. Or do you mean this link: mathoverflow.net/questions/162856/…?

comment Fourier series of functions on compact groups
Is it possible that for continuous $f$ (and for arbitrary compact group $G$) the pointwise convergence can always be understood in some specific sense, like for example the Fejér theorem en.wikipedia.org/wiki/Fej%C3%A9r%27s_theorem suggests?

comment compact-open topology on $B(H)$
Thank you. The definition of Saks space resembles Smith space. I suspect, there is an equivalence in essence...

This is strange, I still can't find... Do you happen to have a file of this paper, so that you could send it to me?

That's interesting. Could you, please, give a more precise reference? I can't find this paper...

As far as I know, it was not translated. I can send you my papers in English on this topic.
