详细研究了跨越独立指数时间的循环贝塞尔过程的持续时间的分布特性。尽管我们的研究可以被认为是 M. Winkel 在 [Wink] 中的一个特例,但这些贝塞尔持续时间的无限可分结构特别丰富,并且我们为这些持续时间的 Levy 度量所产生的一系列随机变量开发了代数性质。
The distributional properties of the duration of a recurrent Bessel process straddling an independent exponential time are studied in detail. Althrough our study may be considered as a particular case of M. Winkel's in [Wink], the infinite divisibility structure of these Bessel durations is particularly rich and we develop algebraic properties for a family of random variables arising from the Levy measures of these durations.
