Multiscale Volatility Analysis for Noisy High-Frequency Prices

open access: yesRisks, 2023
We present a multiscale analysis of the volatility of intraday prices from high-frequency data. Our multiscale framework includes a fractional Brownian motion and microstructure noise as the building blocks.

The flashing Brownian ratchet and Parrondo’s paradox [PDF]

open access: yesRoyal Society Open Science, 2018
A Brownian ratchet is a one-dimensional diffusion process that drifts towards a minimum of a periodic asymmetric sawtooth potential. A flashing Brownian ratchet is a process that alternates between two regimes, a one-dimensional Brownian motion and a ...

The Brownian Motion [PDF]

open access: yes, 2019
This open access textbook is the first to provide Business and Economics Ph.D. students with a precise and intuitive introduction to the formal backgrounds of modern financial theory. It explains Brownian motion, random processes, measures, and Lebesgue integrals intuitively, but without sacrificing the necessary mathematical formalism, making them ...

Hot Brownian Motion [PDF]

open access: yesPhysical Review Letters, 2010
We derive the generalized Markovian description for the non-equilibrium Brownian motion of a heated particle in a simple solvent with a temperature-dependent viscosity. Our analytical results for the generalized fluctuation-dissipation and Stokes-Einstein relations compare favorably with measurements of laser-heated gold nano-particles and provide a ...

A promising new energy source: The Brownian motion of nanoresonator arrays

open access: yesEPJ Web of Conferences, 2014
It is proposed a device designed to extract the Brownian motion energy. Since Brownian motion is usually a whoolly disordered motion, the first step consists in putting it in order with resonators, the Brownian motion of which is organized.

Linear filtering with fractional Brownian motion in the signal and observation processes [PDF]

open access: yes, 1999
Integral equations for the mean-square estimate are obtained for the linear filtering problem, in which the noise generating the signal is a fractional Brownian motion with Hurst index h∈(3/4,1) and the noise in the observation process includes a ...

Impact of Multiplicative Noise on the Exact Solutions of the Fractional-Stochastic Boussinesq-Burger System

open access: yesJournal of Mathematics, 2022
In this paper, we consider the fractional-stochastic Boussinesq-Burger system (FSBBS) generated by the multiplicative Brownian motion. The Jacobi elliptic function techniques are used to create creative elliptic, hyperbolic, and rational fractional ...

Exact power spectra of Brownian motion with solid friction [PDF]

open access: yes, 2012
The accepted version of 'Exact power spectra of Brownian motion with solid friction'(v1: 14 pages, 5 figures; v2: new figures, some text added, typos corrected) was first deposited by Touchette, H., at Cornell University Library Repository(ArXiv).

Müntz linear transforms of Brownian motion [PDF]

open access: yes, 2014
We consider a class of Volterra linear transforms of Brownian motion associated to a sequence of Müntz Gaussian spaces and determine explicitly their kernels; the kernels take a simple form when expressed in terms of Müntz-Legendre polynomials. These are

Hausdorff measure of arcs and Brownian motion on Brownian spatial trees [PDF]

open access: yes, 2009
A Brownian spatial tree is defined to be a pair $(\mathcal{T},\phi)$, where $\mathcal{T}$ is the rooted real tree naturally associated with a Brownian excursion and φ is a random continuous function from $\mathcal{T}$ into ℝd such that, conditional on ...
