Poisson-type processes governed by fractional and higher-order recursive differential equations

TL;DR: In this paper, some fractional extensions of the recursive differential equation governing the Poisson process, by introducing combinations of different fractional time-derivatives, are considered, and the corresponding processes are proved to be renewal, with density of the intearrival times (represented by Mittag-Leffler functions) possessing power, instead of exponential, decay, for t tending to infinite.

Probabilistic analysis of the telegrapher's process with drift by means of relativistic transformations

TL;DR: In this paper, the authors examined the telegrapher's process with drift and its distribution was obtained by applying the Lorentz transformation, and derived the related characteristic function as well as the distribution by solving an initial value problem for the generalized telegraph equation.
Journal ArticleDOI

Fractional pure birth processes

TL;DR: In this paper, a fractional version of the Yule-furry birth process is considered, where fractionality is obtained by replacing the first order time derivative in the difference-differential equations which govern the probability law of the process with the Dzherbashyan-Caputo fractional derivative.
Journal ArticleDOI

Composition of Stochastic Processes Governed by Higher-Order Parabolic and Hyperbolic Equations

TL;DR: In this paper, the authors considered compositions of stochastic processes that are governed by higher-order partial differential equations and showed that the governing higherorder equations that are obtained are either of the usual parabolic type or, as in the last example, of hyperbolic type.
Journal ArticleDOI

Motions with reflecting and absorbing barriers driven by the telegraph equation

TL;DR: In this paper, the authors obtained the explicit distributions of motions governed by the telegraph equation (without drift) when a reflecting and an absorbing barrier is assumed, and the analysis of reflecting and absorbing motions when the initial velocities are fixed.
