Weighted Local Times of a Sub-fractional Brownian Motion as Hida Distributions [PDF]

open access: yesJurnal Matematika Integratif, 2020
The sub-fractional Brownian motion is a Gaussian extension of the Brownian motion. It has the properties of self-similarity, continuity of the sample paths, and short-range dependence, among others.

Adopting Feynman–Kac Formula in Stochastic Differential Equations with (Sub-)Fractional Brownian Motion [PDF]

open access: yesMathematics, 2022
The aim of this work is to establish and generalize a relationship between fractional partial differential equations (fPDEs) and stochastic differential equations (SDEs) to a wider class of stochastic processes, including fractional Brownian motions {BtH,

Search efficiency of discrete fractional Brownian motion in a random distribution of targets

open access: yesPhysical Review Research, 2021
Efficiency of search for randomly distributed targets is a prominent problem in many branches of the sciences. For the stochastic process of Lévy walks, a specific range of optimal efficiencies was suggested under variation of search intrinsic and ...

Lévy Processes Linked to the Lower-Incomplete Gamma Function

open access: yesFractal and Fractional, 2021
We start by defining a subordinator by means of the lower-incomplete gamma function. This can be considered as an approximation of the stable subordinator, easier to be handled in view of its finite activity.

Convergence rate of CLT for the drift estimation of sub-fractional Ornstein–Uhlenbeck process of second kind

open access: yesModern Stochastics: Theory and Applications, 2021
In this paper, we deal with an Ornstein–Uhlenbeck process driven by sub-fractional Brownian motion of the second kind with Hurst index $H\in (\frac{1}{2},1)$.

From sub- to superdiffusion: fractional Brownian motion of membraneless organelles in early C. elegans embryos

open access: yesNew Journal of Physics, 2021
Fractional Brownian motion (FBM) is a prevalent Gaussian stochastic process that has frequently been linked to subdiffusive motion in complex fluids, e.g. inside living cells.

Barrier Option Pricing in the Sub-Mixed Fractional Brownian Motion with Jump Environment

open access: yesFractal and Fractional, 2022
This paper investigates the pricing formula for barrier options where the underlying asset is driven by the sub-mixed fractional Brownian motion with jump.

An extension of sub-fractional Brownian motion [PDF]

open access: yesPublicacions Matemàtiques, 2013
In this paper, firstly, we introduce and study a self-similar Gaussian process with parameters H ∈ (0; 1) and K ∈ (0; 1] that is an extension of the well known sub-fractional Brownian motion introduced by Bojdecki et al. [4]. Secondly, by using a decomposition in law of this process, we prove the existence and the joint continuity of its local time.

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
