comment Why $\|f-g\|=0$ if and only if $f=g$?
Thanks @Winther. But by saying almost everywhere, do we need specify the measure before the definition of this norm?

comment Is the integral finite if the integrand is $o(x^{-1})$?
Thank you @MarioCarneiro! I think the intuition is that there exist a large class of functions that converge to 0 faster than $x^{-1}$ but slower than $x^{-\alpha}$ for any $\alpha < -1$. I think I saw somewhere there's no boundary between convergence and divergence.

comment Show the union of two matching is bipartite
This might work but I'm expecting a much easier answer, which should involve connected component.

I have think over several hours but still unsuccessful.
