Mittag-Leffler Lévy过程

Mittag-Leffler Lévy Processes

Arun Kumar, N. S. Upadhye

摘要:

在这篇文章中,我们介绍了Mittag-Leffler Lévy过程,并提供了两个替代表示这个过程。首先,根据拉普拉斯变换的边缘密度,其次作为一个从属的随机过程。这两种表示在分析过程的性质时都是有用的。由于该过程的整数阶矩不是有限的,我们得到分数阶矩。得到了它的密度函数和相应的Lévy测度密度.进一步证明了该过程的密度重尾性和随机自相似性。我们的结果在几个方向上推广和补充了Mittag-Leffler分布的结果。

英文摘要:

In this article, we introduce Mittag-Leffler Lévy process and provide two alternative representations of this process. First, in terms of Laplace transform of the marginal densities and next as a subordinated stochastic process. Both these representations are useful in analyzing the properties of the process. Since integer order moments for this process are not finite, we obtain fractional order moments. Its density function and corresponding Lévy measure density is also obtained. Further, heavy tailed behavior of densities and stochastic self-similarity of the process is demonstrated. Our results generalize and complement the results available on Mittag-Leffler distribution in several directions.
