Let $X_1,dots,X_n$ be iid random variables with mean $theta$ and variance 1. Let $F_n$ denote the distribution of $sqrtn(barX-theta)$, where $barX=frac1nsum_i=1^nX_i$. Let $Phi$ denote the standard normal distribution. Are there sufficient conditions on the distribution of the $X_i$s so that
$$sup_g left| fracint g(x) dF_n(x)int g(x) dPhi(x) - 1 right| to 0,$$
where the supremum is over all bounded functions on the interval $[0,1]$ (excluding the case $g=0$ $Phi$-a.s.). Convergence in total variation seems not strong enough.

$int g , d Phi$ may be $0$.

Right, thanks! I'll edited the post.

Even excluding the case $g=0$ almost surely, the integral in the denominator may be $0$.

Really? Isn't it equivalent for non-negative functions?
