Stylized Model of Lévy Process in Risk Estimation
Mathematics, 2023 Risk management is a popular and important problem in academia and industry. From a small-scale system, such as city logistics, to a large-scale system, such as the supply chain of a global industrial or financial system, efficient risk management is ...

On extended stochastic integrals with respect to Lévy processes
Karpatsʹkì Matematičnì Publìkacìï, 2013 Let $L$ be a Levy process on $[0,+\infty)$. In particular cases, when $L$ is a Wiener or Poisson process, any square integrable random variable can be decomposed in a series of repeated stochastic integrals from nonrandom functions with respect to $L ...

Multiple Points of Levy Processes
The Annals of Probability, 1989 We prove a conjecture of Hendricks and Taylor that a Levy process in $\mathbb{R}^d$ with 1-potential kernel $u(x)$ will have $k$-multiple points if $\int_{|x| \leq 1} (u(x))^k dx 0$.

Karpatsʹkì Matematičnì Publìkacìï, 2014 The operators of stochastic differentiation, which are closely related with the extended Skorohod stochastic integral and with the Hida stochastic derivative, play an important role in the classical (Gaussian) white noise analysis.

Strong anomalous diffusion in two-state process with Lévy walk and Brownian motion
Physical Review Research, 2020 Strong anomalous diffusion phenomena are often observed in complex physical and biological systems, which are characterized by the nonlinear spectrum of exponents qν(q) by measuring the absolute qth moment 〈|x|^{q}〉.

Karpatsʹkì Matematičnì Publìkacìï, 2019 We deal with spaces of nonregular generalized functions in the Lévy white noise analysis, which are constructed using Lytvynov's generalization of a chaotic representation property.

Lévy processes and quasi-shuffle algebras [PDF]
Stochastics, 2014 We investigate the algebra of repeated integrals of semimartingales. We prove that a minimal family of semimartingales generates a quasi-shuffle algebra. In essence, to fulfill the minimality criterion, first, the family must be a minimal generator of the algebra of repeated integrals generated by its elements and by quadratic covariation processes ...

Investigating Levy's model in financial series prediction(case of vanilla option) [PDF]
Mathematics and Modeling in FinanceIn recent years, there has been growing interest in the application of stochastic processes to model financial markets, particularly in the pricing and prediction of derivative instruments such as options. One of the more advanced models that has emerged

Cognitive Behavioral Therapy for Youth With Childhood‐Onset Lupus: A Randomized Clinical Trial
Arthritis Care &Research, EarlyView.Objective Our objective was to determine the feasibility and acceptability of the Treatment and Education Approach for Childhood‐Onset Lupus (TEACH), a six‐session cognitive behavioral intervention addressing depressive, fatigue, and pain symptoms, delivered remotely to individual youth with lupus by a trained interventionist.
