q-矩消除了与q-傅立叶变换的逆相关联的退化
q-Moments remove the degeneracy associated with the inversion of the q-Fourier transform
摘要:
最近证明[Hilhorst,JSTAT,P10023(2010)],傅立叶变换的q-推广在q > 1的概率密度函数的全空间中是不可逆的。最近还表明,如果我们不仅处理函数本身的q-傅立叶变换,而且处理其所有移位,则这种复杂性消失[Jauregui和Tsallis,Phys. Lett. A 375,2085(2011)]。在这里,我们表明,另一条道路存在完全消除退化与给定的概率密度函数的q-傅立叶变换的逆。事实上,如果我们处理一些与它的q矩有关的额外信息,就有可能确定这个密度。
英文摘要:
It was recently proven [Hilhorst, JSTAT, P10023 (2010)] that the q-generalization of the Fourier transform is not invertible in the full space of probability density functions for q > 1. It has also been recently shown that this complication disappears if we dispose of the q-Fourier transform not only of the function itself, but also of all of its shifts [Jauregui and Tsallis, Phys. Lett. A 375, 2085 (2011)]. Here we show that another road exists for completely removing the degeneracy associated with the inversion of the q-Fourier transform of a given probability density function. Indeed, it is possible to determine this density if we dispose of some extra information related to its q-moments.
