带单侧跳的正自相似马氏过程的退出问题

Exit problems for positive self-similar Markov processes with one-sided jumps

Matija Vidmar

摘要:

本文系统地讨论了具有单侧跳的正自相似马氏过程的标度函数。标度函数表示为与通过Lamperti变换的pssMp基础的谱单侧Lévy过程相关联的通常标度函数的卷积级数。然后,这个理论被带到解决时空:(i)双边退出问题;(ii)联合首次通过问题向上的pssMp和它的乘法下降(分别)。drawup)在光谱负(resp.正)情况下。

英文摘要:

A systematic exposition of scale functions is given for positive self-similar Markov processes (pssMp) with one-sided jumps. The scale functions express as convolution series of the usual scale functions associated with spectrally one-sided Lévy processes that underly the pssMp through the Lamperti transform. This theory is then brought to bear on solving the spatio-temporal: (i) two-sided exit problem; (ii) joint first passage problem upwards for the the pssMp and its multiplicative drawdown (resp. drawup) in the spectrally negative (resp. positive) case.
