用Mellin变换求逆回火稳定从属子及相关过程的密度

Densities of Inverse Tempered Stable Subordinators and Related Processes With Mellin Transforrm

Neha Gupta, Arun Kumar

摘要:

本文利用Mellin变换得到了回火稳定和逆回火稳定从属子的概率密度的无穷级数形式。进一步计算了稳定从属子和逆稳定从属子的乘积和乘积的密度。这些密度的渐近行为被获得为$x \rightarrow 0^+$。回火和逆回火稳定从属类似的结果进行了讨论。我们的研究结果提供了替代方法来找到这些从属的密度,并补充文献中的结果。

英文摘要:

In this article, the infinite series form of the probability densities of tempered stable and inverse tempered stable subordinators are obtained using Mellin transform. Further, the densities of the products and quotients of stable and inverse stable subordinators are worked out. The asymptotic behaviours of these densities are obtained as $x \rightarrow 0^+$. Similar results for tempered and inverse tempered stable subordinators are discussed. Our results provide alternative methods to find the densities of these subordinators and complement the results available in literature.
