A set-indexed fractional Brownian motion [PDF]

open access: yesarXiv, 2005
We define and prove the existence of a fractional Brownian motion indexed by a collection of closed subsets of a measure space. This process is a generalization of the set-indexed Brownian motion, when the condition of independance is relaxed. Relations with the Levy fractional Brownian motion and with the fractional Brownian sheet are studied.

Asian Option Pricing with Monotonous Transaction Costs under Fractional Brownian Motion

open access: yesJournal of Applied Mathematics, 2013
Geometric-average Asian option pricing model with monotonous transaction cost rate under fractional Brownian motion was established. The method of partial differential equations was used to solve this model and the analytical expressions of the Asian ...

A strong uniform approximation of sub-fractional Brownian motion [PDF]

open access: yesarXiv, 2012
Sub-fractional Brownian motion is a process analogous to fractional Brownian motion but without stationary increments. In \cite{GGL1} we proved a strong uniform approximation with a rate of convergence for fractional Brownian motion by means of transport processes.

Nonparametric Regression with Subfractional Brownian Motion via Malliavin Calculus

open access: yesAbstract and Applied Analysis, 2014
We study the asymptotic behavior of the sequence Sn=∑i=0n-1K(nαSiH1)(Si+1H2-SiH2), as n tends to infinity, where SH1 and SH2 are two independent subfractional Brownian motions with indices H1 and H2, respectively. K is a kernel function and the bandwidth

Boundary controllability of nonlocal Hilfer fractional stochastic differential systems with fractional Brownian motion and Poisson jumps

open access: yesAdvances in Differential Equations, 2019
By using stochastic analysis, fractional analysis, compact semigroups and the Schauder fixed-point theorem, we discuss the approximate boundary controllability of a nonlocal Hilfer fractional stochastic differential system with fractional Brownian motion

Bayesian model selection with fractional Brownian motion [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2018
We implement Bayesian model selection and parameter estimation for the case of fractional Brownian motion with measurement noise and a constant drift. The approach is tested on artificial trajectories and shown to make estimates that match well with the ...

On the sub-mixed fractional Brownian motion [PDF]

open access: yesarXiv, 2012
Let ${S_t^H, t \geq 0} $ be a linear combination of a Brownian motion and of an independent sub-fractional Brownian motion with Hurst index $0 < H < 1$. Its main properties are studied and it is shown that $S^H $ can be considered as an intermediate process between a sub-fractional Brownian motion and a mixed fractional Brownian motion.
