comment What kind of convergence is $\sum |f_n|$?
And in case, when we say the radius of convergence of the power series $\sum a_nx^n$ is $r$, are we saying $\sum a_nx^n$ converges pointwise on $(-r, r)$ ?

comment How many sequence of functions are there to converge pointwise to a given function on $E\subseteq \mathbb R$?
Awsome !! thanks to all of you. I am satisfied. Let me see if I can improve further on or not. Thank you once again @Bungo \Quickbeam2k1

@Bungo WOW!! thats cool. And in case, we are to search for series of functions to converge to f, then?

Patrick Da Silva, So, in case, if we have only one of $G$ and $H$ as group structure and the other as set, still it wont work?

And moreover sir, suppose that neither $G$ nor $H$ are groups but simply two ordinary sets. In that case, will your idea work?

That was cool sir! very impressive and helpful idea for me. Thank you. Would you please specify what will happen for isomorphic case?
