Moments of Gamma type and the Brownian supremum process area

Svante Janson

摘要:

我们研究正随机变量,其矩可以表示为产品和Γ函数,这包括许多标准分布。给出了密度函数的存在性、级数展开和渐近性的一般结果。证明了布朗运动的上确界过程的积分具有这类矩,以及线性位移散列研究中出现的一个相关的随机变量,并将一般结果应用于这些变量。

英文摘要:

We study positive random variables whose moments can be expressed by products and quotients of Gamma functions; this includes many standard distributions. General results are given on existence, series expansion and asymptotics of density functions. It is shown that the integral of the supremum process of Brownian motion has moments of this type, as well as a related random variable occuring in the study of hashing with linear displacement, and the general results are applied to these variables.
