Laplace-Laplace analysis of the fractional Poisson process

open access: yes, 2012
We generate the fractional Poisson process by subordinating the standard Poisson process to the inverse stable subordinator. Our analysis is based on application of the Laplace transform with respect to both arguments of the evolving probability densities.

Tempered fractional Poisson processes and fractional equations with Z-transform [PDF]

open access: yesStochastic Analysis and Applications, 2020
In this article, we derive the state probabilities of different type of space- and time-fractional Poisson processes using z-transform. We work on tempered versions of time-fractional Poisson process and space-fractional Poisson processes. We also introduce Gegenbauer type fractional differential equations and their solutions using z-transform.

Compositions, Random Sums and Continued Random Fractions of Poisson and Fractional Poisson Processes [PDF]

open access: yesJournal of Statistical Physics, 2012
In this paper we consider the relation between random sums and compositions of different processes. In particular, for independent Poisson processes $N_α(t)$, $N_β(t)$, $t>0$, we show that $N_α(N_β(t)) \overset{\text{d}}{=} \sum_{j=1}^{N_β(t)} X_j$, where the $X_j$s are Poisson random variables. We present a series of similar cases, the most general

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.
