关于谱负Lévy过程的$q$ -尺度函数

On $q$-scale functions of spectrally negative Lévy processes

Anita Behme, David Oechsler, René L. Schilling

摘要:

我们获得了任意谱负Lévy过程的$q$尺度函数的级数展开式,包括具有无限跳活动的过程,并利用这些展开式导出了各种新的显式$q$尺度函数的例子.此外,我们还研究了具有无穷跳活动的谱负Lévy过程的$q$ -尺度函数的光滑性.这补充了Chan等人[7]关于具有高斯分量或有界变差的谱负Lévy过程的先前结果。

英文摘要:

We obtain series expansions of the $q$-scale functions of arbitrary spectrally negative Lévy processes, including processes with infinite jump activity, and use these to derive various new examples of explicit $q$-scale functions. Moreover, we study smoothness properties of the $q$-scale functions of spectrally negative Lévy processes with infinite jump activity. This complements previous results of Chan et al. [7] for spectrally negative Lévy processes with Gaussian component or bounded variation.
