On the mixed fractional Brownian motion time changed by inverse α-stable subordinator

, 2020
A time-changed mixed fractional Brownian motion by inverse αstable subordinator with index α ∈ (0, 1) is an iterated process Y H Tα(a, b) constructed as the superposition of mixed fractional Brownian motion NH(a, b) and an independent inverse α-stable ...

A note on the correlation matrix of fractional Brownian motion

International Mathematical Forum, 2019
Let XH(t) be a fractional Brownian motion with index H (1/2 < H < 1), and let Dn(t0, t1, . . . tn) (0 ≤ t0 < t1 < · · · < tn) denote the correlation matrix of {X(tk)−X(tk−1) : k = 1, . . . , n}. In this paper, we give an evaluation of detDn.

Stochastic Differential Equations Driven by Multifractional Brownian Motion and Poisson Point Process

Journal of Partial Differential Equations, 2019
In this paper, we study a class of stochastic differential equations with additive noise that contains a non-stationary multifractional Brownian motion (mBm) with a Hurst parameter as a function of time and a Poisson point process of class (QL).

Stochastic Calculus with a Special Generalized Fractional Brownian Motion

International Journal of Applied Mathematics and Simulation
This work is a first step toward developing a stochastic calculus theory with respect to the generalized fractional Brownian motion, which a recently introduced Gaussian process is extending both fractional and sub-fractional Brownian motions.
