关于稳定密度的一些分析性质

On some analytical properties of stable densities

Sonia Fourati

摘要:

L.Bondesson [1]证明了正$α$稳定分布的密度是双曲完全单调的当且仅当$α$ $\le$ 1/2.最近,P. Bosch和Th.西蒙,谁也证实了这一结果的加强版本。我们反驳这个猜想以及相关的猜想Bondesson,同时给一个简短的新的证明的初始猜想,作为一个新的代数性质的HCM和广义Gamma卷积密度(GGC在短),我们建立的直接后果。

英文摘要:

L.Bondesson [1] conjectured that the density of a positive $α$-stable distribution is hyperbolically completely monotone (HCM in short) if and only if $α$ $\le$ 1/2. This was proved recently by P. Bosch and Th. Simon, who also conjectured a strengthened version of this result. We disprove this conjecture as well as a correlated conjecture of Bondesson, while giving a short new proof of the initial conjecture, as a direct consequence of a new algebraic property of HCM and Generalized Gamma convolution densities (GGC in short) which we establish.
