S-asymptotically ω-periodic solutions in distribution for a class of stochastic fractional functional differential equations

In this paper, we introduce the concept of an S-asymptotically ω-periodic process in distribution for the first time, and by means of the successive approximation and the Banach contraction mapping principle, respectively, we obtain sufficient conditions for the existence and uniqueness of the S-asymptotically ω-periodic solutions in distribution for a class of stochastic fractional functional differential equations.
