Abstract
In this paper, we have studied stochastic differential equations with unbounded delay in fractional power spaces perturbed by fractional Ornstein–Uhlenbeck process YH,ξ(t){{Y^{H,\xi}}(t)} with H∈(12,1){H\in(\frac{1}{2},1)}. Subsequently, the existence and uniqueness of mild solution of the considered equation have been proved with fixed-point theorem. Finally, we obtain the global attracting set of the considered equations by some stochastic analysis and inequality technique.
