Multiscaling asymptotic behavior of solutions to random high-order heat equations

Maha Mosaad A Alghamdi, Nikolai Leonenko, Andriy Olenko

This paper studies high-order partial differential equations with random initial conditions that have both long-memory and cyclic behavior. The cases of random initial conditions w…

Tossing half-coins and other partial coins: signed probabilities and Sibuya distribution

Nikolai Leonenko, Igor Podlubny

A method for the numerical simulation of signed probability distributions for the case of tossing -th of a coin is presented and illustrated by examples.

Construction and limit theorems for supCAR fields

Illia Donhauzer, Nikolai Leonenko, Andriy Olenko

The paper introduces a new class of random fields, supCAR fields, which are constructed as superpositions of continuous autoregressive random fields. These supCAR fields possess in…

Stretched non-local Pearson diffusions

Luisa Beghin, Nikolai Leonenko, Ivan Papić +1

We define a novel class of time changed Pearson diffusions, termed stretched non local Pearson diffusions, where the stochastic time change model has the Kilbas Saigo function as i…

Sibuya probability distributions and numerical evaluation of fractional-order operators

Nikolai Leonenko, Igor Podlubny

In this work we explore the Sibuya discrete probability distribution, which serves as the basis and the main instrument for numerical simulations of Grunwald--Letnikov fractional d…

Relaxation equations with stretched non-local operators: renewal and time-changed processes

Luisa Beghin, Nikolai Leonenko, Jayme Vaz

We introduce and study renewal processes defined by means of extensions of the standard relaxation equation through ``stretched" non-local operators (of order and with paramete…
