A Simple Construction of the Fractional Brownian Motion

چکیده
In this work we introduce correlated random walks on Z. When picking suitably at random the coefficient of correlation, and taking the average over a large number of walks, we obtain a discrete Gaussian process, whose scaling limit is the fractional Brownian motion. We have to use two radically different models for both cases 1 2 ≤ H < 1 and 0 < H < 1 2 . This result provides an algorithm for the simulation of the fractional Brownian motion, which appears to be quite efficient.

On time-dependent neutral stochastic evolution equations with a fractional Brownian motion and infinite delays
In this paper, we consider a class of time-dependent neutral stochastic evolution equations with the infinite delay and a fractional Brownian motion in a Hilbert space. We establish the existence and uniqueness of mild solutions for these equations under non-Lipschitz conditions with Lipschitz conditions being considered as a special case. An example is provided to illustrate the theory
متن کاملFractional Brownian fields, duality, and martingales
In this paper the whole family of fractional Brownian motions is constructed as a single Gaussian field indexed by time and the Hurst index simultaneously. The field has a simple covariance structure and it is related to two generalizations of fractional Brownian motion known as multifractional Brownian motions. A mistake common to the existing literature regarding multifractional Brownian moti...
متن کاملA connection between the stochastic heat equation and fractional Brownian motion, and a simple proof of a result of Talagrand
We give a new representation of fractional Brownian motion with Hurst parameter H ≤ 12 using stochastic partial differential equations. This representation allows us to use the Markov property and time reversal, tools which are not usually available for fractional Brownian motion. We then give simple proofs that fractional Brownian motion does not hit points in the critical dimension, and that ...
