Multiplicative strong unimodality for positive stable laws

Probability 2010-03-01 v1

Abstract

It is known that real Non-Gaussian stable distributions are unimodal, not additive strongly unimodal, and multiplicative strongly unimodal in the symmetric case. By a theorem of Cuculescu-Theodorescu, the only remaining relevant situation for the multiplicative strong unimodality of stable laws is the one-sided. In this paper, we show that positive α\alpha-stable laws are multiplicative strongly unimodal iff α1/2.\alpha\le 1/2.
