In this paper,we are concerned with the existence and uniqueness of mild solution for a class of nonlinear fractional Sobolev-type stochastic differential equations driven by fractional Brownian motion with Hurst parameter H∈ (1/2,1) in Hilbert space.We obtain the required result by using semigroup theory,stochastic analysis principle,fractional calculus and Picard iteration techniques with some non-Lipschitz conditions.
