On the Integral of the Fractional Brownian Motion and Some Pseudo-Fractional Gaussian Processes

open access: yesMathematics, 2019
We investigate the main statistical parameters of the integral over time of the fractional Brownian motion and of a kind of pseudo-fractional Gaussian process, obtained as a classical Gauss−Markov process from Doob representation by replacing ...

Maximal Brownian motions

open access: yesAnnales de l'Institut Henri Poincaré, Probabilités et Statistiques, 2009
Let $Z=(X,Y)$ be a planar Brownian motion, $\ZZ$ the filtration it generates, and $B$ a linear Brownian motion in the filtration $\ZZ$. One says that $B$ (or its filtration) is maximal if no other linear $\ZZ$-Brownian motion has a filtration strictly bigger than that of $B$.

Cluster Analysis on Locally Asymptotically Self-Similar Processes with Known Number of Clusters

open access: yesFractal and Fractional, 2022
We conduct cluster analysis of a class of locally asymptotically self-similar stochastic processes with finite covariance structures, which includes Brownian motion, fractional Brownian motion, and multifractional Brownian motion as paradigmatic examples.

Nonlinear Brownian Motion [PDF]

open access: yesPhysics-Uspekhi, 1994
Brownian motion is a familiar classroom demonstration. This phenomenon was discovered as early as 1827 by a British botanist called Robert Brown who was the first to report incessant chaotic movement of pollen particles suspended in liquid.

Operator Fractional Brownian Motion and Martingale Differences

open access: yesAbstract and Applied Analysis, 2014
It is well known that martingale difference sequences are very useful in applications and theory. On the other hand, the operator fractional Brownian motion as an extension of the well-known fractional Brownian motion also plays an important role in both

Superstatistical Brownian Motion [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2006
As a main example for the superstatistics approach, we study a Brownian particle moving in a d-dimensional inhomogeneous environment with macroscopic temperature fluctuations. We discuss the average occupation time of the particle in spatial cells with a given temperature.

Thermo diffusion and diffusion thermo impacts on bioconvection Walter-B nanomaterial involving gyrotactic microorganisms

open access: yesAlexandria Engineering Journal, 2021
Here magnetohydrodynamic (MHD) bioconvection Walter-B nanofluid flow due to stretched sheet is considered. Significance of motile gyrotactic microorganisms and melting phenomena are scrutinized.

The rapid points of a complex oscillation [PDF]

open access: yesLogical Methods in Computer Science, 2012
By considering a counting-type argument on Brownian sample paths, we prove a result similar to that of Orey and Taylor on the exact Hausdorff dimension of the rapid points of Brownian motion.
