Abstract

In a recent paper Hilhorst \cite{Hilhorst2010} illustrated that the qq-Fourier transform for q>1q>1 is not invertible in the space of density functions. Using an invariance principle he constructed a family of densities with the same qq-Fourier transform and claimed that qq-Gaussians are not mathematically proved to be attractors. We show here that none of the distributions constructed in Hilhorst's counterexamples can be a limit distribution in the qq-CLT, except the one whose support covers the whole real axis, which is precisely the qq-Gaussian distribution.
