Functional limit theorems for L\'evy processes satisfying Cram\'er's condition

Probability 2011-04-26 v1

Abstract

We consider a L\'evy process that starts from x<0x<0 and conditioned on having a positive maximum. When Cram\'er's condition holds, we provide two weak limit theorems as xx\to -\infty for the law of the (two-sided) path shifted at the first instant when it enters (0,)(0,\infty), respectively shifted at the instant when its overall maximum is reached. The comparison of these two asymptotic results yields some interesting identities related to time-reversal, insurance risk, and self-similar Markov processes.
