On a subclass of Bazileviv c functions

For $ alpha>0$, $ 0le eta<1$, we denote $ B_1(alpha,eta)$ to be the class of normalised analytic functions satisfying the condition $ ReBig({f(z)over z}Big)^{alpha-1}f'(z)>eta$ for $ z$ in the unit disc $ D={z:|z|<1}$. Sharp estimates for $ ReBig({f(z)over z}Big)^alpha$ is established. In fact a more generalished result concerning iterated integrals is obtained
