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.

Random representation of Blasius’ formula through stochastic complex integrals

open access: yesInternational Journal of Mathematics for Industry, 2019
Two-dimensional flow is considered in the complex plane. We discuss Blasius’ formula in a perfect fluid through stochastic complex integrals. This formula is also investigated in a viscous fluid.

Continuous-time random walks and Lévy walks with stochastic resetting

open access: yesPhysical Review Research, 2020
Intermittent stochastic processes appear in a wide field, such as chemistry, biology, ecology, and computer science. This paper builds up the theory of intermittent continuous-time random walk (CTRW) and Lévy walk, in which the particles are ...

Transportation distance between the Lévy measures and stochastic equations for Lévy-type processes

open access: yesModern Stochastics: Theory and Applications, 2014
The notion of the transportation distance on the set of the Lévy measures on $\mathbb{R}$ is introduced. A Lévy-type process with a given symbol (state dependent analogue of the characteristic triplet) is proved to be well defined as a strong solution to

Voltage drop across Josephson junctions for Lévy noise detection

open access: yesPhysical Review Research, 2020
We propose to characterize Lévy-distributed stochastic fluctuations through the measurement of the average voltage drop across a current-biased Josephson junction.

Option Pricing under a Generalized Black–Scholes Model with Stochastic Interest Rates, Stochastic Strings, and Lévy Jumps

open access: yesMathematics, 2023
We introduce a novel option pricing model that features stochastic interest rates along with an underlying price process driven by stochastic string shocks combined with pure jump Lévy processes.

A functional limit theorem for stochastic integrals driven by a time-changed symmetric α-stable Lévy process [PDF]

open access: yes, 2014
Under proper scaling and distributional assumptions, we prove the convergence in the Skorokhod space endowed with the M1-topology of a sequence of stochastic integrals of a deterministic function driven by a time-changed symmetric α-stable Lévy process ...

Continuous Time Autoregressive Moving Average Processes Driven by Semi-Levy Process

open access: yesپژوهش‌های ریاضی, 2020
Introduction A flexible and tractable class of linear models is Autoregressive moving average (ARMA) process that are in effect of discrete noises.  The continuous time ARMA (CARMA) processes have wide applications in many data modeling where are more ...

Weak Multilevel Path Simulation for Jump-Diffusion Assets

open access: yesپژوهش‌های ریاضی, 2021
This paper, inspired by recent advances in the application of the multilevel Monte-Carlo (MLMC) approach to Lévy driven assets, is based on the valuation of financial derivatives.

New stochastic processes to model interest rates : LIBOR additive processes [PDF]

open access: yes, 2008
In this paper, a new kind of additive process is proposed. Our main goal is to define, characterize and prove the existence of the LIBOR additive process as a new stochastic process.
