Existence and uniqueness of mild solutions to neutral impulsive fractional stochastic delay differential equations driven by both Brownian motion and fractional Brownian motion

In this paper, we discuss the existence and uniqueness of a mild solution for neutral impulsive fractional stochastic delay differential equations driven by Brownian motion, and fractional Brownian motion with the Hurst parameter H (1/2,1) , by using Banach fixed point theorem in a Hilbert space.
