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.

Combinatorial Lévy processes [PDF]

open access: yesThe Annals of Applied Probability, 2018
Combinatorial Levy processes evolve on general state spaces of countable combinatorial structures. In this setting, the usual Levy process properties of stationary, independent increments are defined in an unconventional way in terms of the symmetric difference operation on sets.

Profits: The Views of Jerome Levy and Michal Kalecki [PDF]

open access: yes
Profits are the incentive for production and therefore employment in almost all of the world's economies; they also may represent exploitation of workers and consumers.

Cliquet option pricing with Meixner processes

open access: yesModern Stochastics: Theory and Applications, 2018
We investigate the pricing of cliquet options in a geometric Meixner model. The considered option is of monthly sum cap style while the underlying stock price model is driven by a pure-jump Meixner–Lévy process yielding Meixner distributed log-returns ...

Lévy processes conditioned to stay in a half-space with applications to directional extremes

open access: yesModern Stochastics: Theory and Applications, 2022
This paper provides a multivariate extension of Bertoin’s pathwise construction of a Lévy process conditioned to stay positive or negative. Thus obtained processes conditioned to stay in half-spaces are closely related to the original process on a ...

Refracted Lévy processes

open access: yesAnnales de l'Institut Henri Poincaré, Probabilités et Statistiques, 2010
Motivated by classical considerations from risk theory, we investigate boundary crossing problems for refracted Lévy processes. The latter is a Lévy process whose dynamics change by subtracting off a fixed linear drift (of suitable size) whenever the aggregate process is above a pre-specified level.

Cliquet option pricing in a jump-diffusion Lévy model

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 ...

Nonlinear Stochastic SIS Epidemic Model Incorporating Lévy Process

open access: yesComplexity, 2022
In this work, we study a stochastic SIS epidemic model with Lévy jumps and nonlinear incidence rates. Firstly, we present our proposed model and its parameters.

Lévy laplacians and annihilation process

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2018
The Lévy Laplacians are infinite-dimensional Laplace operators defined as the Cesaro mean of the second-order directional derivatives. In the theory of Sobolev–Schwarz distributions over a Gaussian measure on an infinite-dimensional space (the Hida ...
