L\'evy processes with jumps governed by lower incomplete gamma subordinator and its variations

Probability 2024-05-17 v2

Abstract

In this paper, we study the L\'evy process time-changed by independent L\'evy subordinators, namely, the incomplete gamma subordinator, the ϵ\epsilon-jumps incomplete gamma subordinator and tempered incomplete gamma subordinator. We derive their important distributional properties such as mean, variance, correlation, tail probabilities and fractional moments. The long-range dependence property of these processes are discussed. An application in insurance domain is studied in detail. Finally, we present the simulated sample paths for the subordinators.
