Adaptive Lévy processes and area-restricted search in human foraging. [PDF]

open access: yesPLoS ONE, 2013
A considerable amount of research has claimed that animals' foraging behaviors display movement lengths with power-law distributed tails, characteristic of Lévy flights and Lévy walks.

Cliquet option pricing in a jump-diffusion Lévy model [PDF]

open access: yesModern Stochastics: Theory and Applications, 2018
We investigate the pricing of cliquet options in a jump-diffusion model. The considered option is of monthly sum cap style while the underlying stock price model is driven by a drifted Lévy process entailing a Brownian diffusion component as well as ...

A Fourier cosine expansion method for pricing FX-TARN under Lévy processes

open access: yesQuantitative Finance and Economics, 2023
In this paper, we extend the Fourier cosine expansion (COS) method to the pricing of {foreign exchange} target redemption note (FX-TARN), a popular exotic currency option.

Finite-time stability and optimal control of an impulsive stochastic reaction-diffusion vegetation-water system driven by Lévy process with time-varying delay

open access: yesMathematical Biosciences and Engineering, 2021
In this paper, a reaction-diffusion vegetation-water system with time-varying delay, impulse and Lévy jump is proposed. The existence and uniqueness of the positive solution are proved. Meanwhile, mainly through the principle of comparison, we obtain the

On Wick calculus and its relationship with stochastic integration on spaces of regular test functions in the Lévy white noise analysis

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
We deal with spaces of regular test functions in the Lévy white noise analysis, which are constructed using Lytvynov's generalization of a chaotic representation property.

Extension of Short Rate Model Under a Lévy Process

open access: yesFountain Journal of Natural and Applied Sciences (FUJNAS), 2023
A lot of abnormalities occur in real-life scenarios, thus leading to some difficulties in modelling such scenarios without a deeper understanding of certain aspects of Lévy processes.
