Entropy of Wiener integrals with respect to fractional Brownian motion

Iryna Bodnarchuk, Yuliya Mishura, Kostiantyn Ralchenko

The paper is devoted to the properties of the entropy of the exponent-Wiener-integral fractional Gaussian process (EWIFG-process), that is a Wiener integral of the exponent with re…

Entropies of the Poisson distribution as functions of intensity: "normal" and "anomalous" behavior

Dmitri Finkelshtein, Anatoliy Malyarenko, Yuliya Mishura +1

The paper extends the analysis of the entropies of the Poisson distribution with parameter . It demonstrates that the Tsallis and Sharma-Mittal entropies exhibit monotonic behav…

Fractional Gaussian noise: Projections, prediction, norms

Iryna Bodnarchuk, Yuliya Mishura, Kostiantyn Ralchenko

We examine the one-sided and two-sided (bilateral) projections of an element of fractional Gaussian noise onto its neighboring elements. We establish several analytical results and…

Discretization of integrals driven by multifractional Brownian motions with discontinuous integrands

Kostiantyn Ralchenko, Foad Shokrollahi, Tommi Sottinen

We establish the rate of convergence in the -norm for equidistant approximations of stochastic integrals with discontinuous integrands driven by multifractional Brownian motio…

Fractional diffusion Bessel processes with Hurst index

Yuliya Mishura, Kostiantyn Ralchenko

We introduce fractional diffusion Bessel process with Hurst index , derive a stochastic differential equation for it, and study the asymptotic properties of its sa…

Entropy and alternative entropy functionals of fractional Gaussian noise as the functions of Hurst index

Anatoliy Malyarenko, Yuliya Mishura, Kostiantyn Ralchenko +1

This paper is devoted to the study of the properties of entropy as a function of the Hurst index, which corresponds to the fractional Gaussian noise. Since the entropy of the Gauss…
