On Partial Sums of the Libera Integral Operator

Let S be the class of functions f z. which are analytic and univalent in the open unit disk U with f 0.s0 and f X 0.s1. The nth partial sums of the Libera integral operator F z. for f z.gS are denoted by Sn z, F.. In the present paper, the starlikeness property of Sn z, F. is proved
