A New Fractional Poisson Process Governed by a Recursive Fractional Differential Equation

open access: yesFractal and Fractional, 2022
This paper proposes a new fractional Poisson process through a recursive fractional differential governing equation. Unlike the homogeneous Poison process, the Caputo derivative on the probability distribution of k jumps with respect to time is linked to

Some Compound Fractional Poisson Processes

open access: yesFractal and Fractional, 2022
In this paper, we introduce and study fractional versions of the Bell–Touchard process, the Poisson-logarithmic process and the generalized Pólya–Aeppli process.

Non-Local Seismo-Dynamics: A Fractional Approach

open access: yesFractal and Fractional, 2022
This paper consists of a general consideration of a seismic system as a subsystem of another, larger system, exchanging with it by extensive dynamical quantities in a sequential push mode.

Quasi-likelihood Estimation in Fractional Levy SPDEs from Poisson Sampling

open access: yesEuropean Journal of Mathematical Analysis, 2022
We study the quasi-likelihood estimator of the drift parameter in the stochastic partial differential equations driven by a cylindrical fractional Levy process when the process is observed at the arrival times of a Poisson process.

Fractional Model of the Deformation Process

open access: yesFractal and Fractional, 2022
The article considers the fractional Poisson process as a mathematical model of deformation activity in a seismically active region. The dislocation approach is used to describe five modes of the deformation process.

Biased Continuous-Time Random Walks with Mittag-Leffler Jumps

open access: yesFractal and Fractional, 2020
We construct admissible circulant Laplacian matrix functions as generators for strictly increasing random walks on the integer line. These Laplacian matrix functions refer to a certain class of Bernstein functions.

Fractional Criticality Theory and Its Application in Seismology

open access: yesFractal and Fractional, 2023
To understand how the temporal non-locality («memory») properties of a process affect its critical regimes, the power-law compound and time-fractional Poisson process is presented as a universal hereditary model of criticality.

Аппроксимация законов распределения времён ожидания форшоков на основе дробной модели деформационной активности

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2022
В статье рассматриваются два алгоритма построения последовательностей форшоков, связанных с главным событием заданной энергии, на основе ранее разработанной авторами статистической модели деформационного процесса.

Skellam Type Processes of Order k and Beyond

open access: yesEntropy, 2020
In this article, we introduce the Skellam process of order k and its running average. We also discuss the time-changed Skellam process of order k. In particular, we discuss the space-fractional Skellam process and tempered space-fractional Skellam ...

NON-CONVEX HYBRID TOTAL VARIATION FOR RESTORING MEDICAL IMAGE CORRUPTED BY POISSON NOISE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2023
In this work, we proposed the hybrid non-convex regularizers for Poisson noise removal on medical images. The model is built by a combination of non-convex total variation and non-convex fractional total variation.
