摘要

This paper discusses the fractional stochastic neutral evolution equation driven by a fractional Brownian motion. The existence of square-mean S-asymptotically periodic mild solutions for the associated stochastic evolution equation driven by a fractional Brownian motion is established. Some new existence results of mean square S-asymptotically periodic mild solutions for neutral fractional stochastic evolution equation are showed by means of the operator semigroup theory, stochastic analysis and fixed point theorems.
