comment $\lim_{n\rightarrow \infty}\int_0^1f_nhdm=\int_0^1fhdm$, prove $f\in L^p(m)$ , where $1\le p<\infty$.
It is Lebesgue measure, but I dont know what is weak-compactness

comment $X$ is locally compact Hausdorff space, $\mu$ is Borel regular measure. How to prove $\mu$ is cover $[0,\mu(A)]$
yes, that is what I want to prove.

comment $f_n$ $\in$ $L_2(\mu)$, the limit $ f \in L_2(\mu)$
I got that just need make a little change of your counterexample,when u(x) is finite,$f_n:=\sqrt{ n(n+1) }\chi_{(1/(n+1),1/n}$,consider [0,1].

Thanks, I am considering when u(x) is finite, is that convergence in $L^2$ right?
