Abstract

‎Let $\mathcal{A}$ denote the class of functions $f$ that are analytic in the unit disk $\Delta$ with normalization $f(0)=f^{\prime}(0)-1=0$‎. ‎In this paper conditions are determined for strongly starlikeness of the Libera transform‎. ‎The results of Mocanu and Nunokawa et al‎. ‎are improved‎.
