Median, Concentration and Fluctuations for Lévy Processes
نویسندگان
چکیده
We estimate a median of f(Xt) where f is a Lipschitz function, X is a Lévy process and t is an arbitrary time. This leads to concentration inequalities for f(Xt). In turn, corresponding fluctuation estimates are obtained under assumptions typically satisfied if the process has a regular behavior in small time and a, possibly different, regular behavior in large time.

In this short paper, we show how fluctuation identities for Lévy processes with no positive jumps yield the distribution of the present value of dividends paid until ruin in a Lévy insurance risk model with a dividend barrier.
متن کاملOn Extreme Ruinous Behaviour of Lévy Insurance Risk Processes
In this short note we show how new fluctuation identities and their associated asymptotics given in Vigon (2002), Klüppelberg et al. (2004) and Doney and Kyprianou (2006) provide the basis for establishing, in an elementary way, asymptotic overshoot and undershoot distribitions for a general class of Lévy insurance risk processes. The results bring the earlier conclusions of Asmussen and Klüppe...
متن کاملLévy processes and continuous-state branching processes: part II
In this section we discuss a simple feature of all Lévy processes which follows as a direct consequence of stationary independent increments. That is, when the path of a Lévy process over a finite time horizon is time reversed (in an appropriate sense) the new path is equal in law to the process reflected about the origin. This property will prove to be of crucial importance in a number of fluc...
متن کاملHeteroskedastic Lévy flights
Truncated Lévy flights are random walks in which the arbitrarily large steps of a Lévy flight are eliminated. Since this makes the variance finite, the central limit theorem applies, and as time increases the probability distribution of the increments becomes Gaussian. Here, truncated Lévy flights with correlated fluctuations of the variance (heteroskedasticity) are considered. What makes these...
