“…Fractional stochastic delay differential equations, in which b = 0 and Z = B H , were considered in only few papers. For H > 1/2, the existence and uniqueness of solution under different sets of assumptions was established in [1,2,3,4,5,8]. In the case H > 1/3, the existence and uniqueness of solution was shown in [14] for coefficients of the form f (X(t), X(t − r 1 ), X(t − r 2 ), .…”
