To remove the hypothesis that $w$ has finite variance, note that if $w$ is a probability density with zero mean and infinite variance, $\star^n w(n^{1/2}x)n^{d/2}$ is ``trying'' to converge to a ``Gaussian of infinite variance''. In particular, one would expect that for all $R>0$, \begin{equation}\label{CLT2} @@ -1,3 +1,8 @@ +v1.1: + + * Fixed: Typo: c_n\sim n^{-3/2} not n^{3/2} + + v1.0: * Fixed: Missing factor of 1/2 in expansion of f. |
