Analytical Solutions for Multi-Time Scale Fractional Stochastic Differential Equations Driven by Fractional Brownian Motion and Their Applications

Abstract

Abstract:In this paper, we investigate analytical solutions of multi-time scale fractional stochastic differential equations driven by fractional Brownian motions. We firstly decompose homogeneous multi-time scale fractional stochastic differential equations driven by fractional Brownian motions into independent differential subequations, and give their analytical solutions. Then, we use the variation of constant parameters to obtain the solutions of nonhomogeneous multi-time scale fractional stochastic differential equations driven by fractional Brownian motions. Finally, we give three examples to demonstrate the applicability of our obtained results.

Stochastic Entropy Solutions for Stochastic Scalar Balance Laws

“…However, if F depends on spatial variables, i.e., F = F(x, ρ), we can also establish a stochastic kinetic formulation up to a long and tedious calculations. In particular, for F(x, ρ) = b(x)F 1 (ρ), B i,j = 0 and A(t, x, ρ)dt is replaced by A(ρ)dW t , we refer to [27], and for F(x, ρ) = b(x)F 1 (ρ), B i,j = δ i,j ρ and A(t, x, ρ) = 0, to [28], and some related work, to [29].…”

Existence and Stability of Solutions of Fuzzy Fractional Stochastic Differential Equations with Fractional Brownian Motions

“…Jialu Zhu et al, in [8], prove existence of solutions to SDEs with fBm. Ding and Nieto [9] investigated analytical solutions of multitime-scale FSDEs driven by fBm. Vas'kovskii et al [10] prove that the pth moments, p ≥ 1, of strong solutions of a mixed-type SDEs are driven by a standard Brownian motion and a fBm.…”
