Large Deviations for Clocks of Self-similar Processes

Part of the Lecture Notes in Mathematics book series (LNM, volume 2137)


The Lamperti correspondence gives a prominent role to two random time changes: the exponential functional of a Lévy process drifting to \(\infty\) and its inverse, the clock of the corresponding positive self-similar process. We describe here asymptotical properties of these clocks in large time, extending the results of Yor and Zani (Bernoulli 7, 351–362, 2001).



The authors want to thank Frédérique Petit for valuable conversations on the Cauchy clock.
