Region of variability for exponentially convex univalent functions

S. Ponnusamy, A. Vasudevarao, M. Vuorinen

For $α\in\IC\setminus \{0\}$ let $\mathcal{E}(\alpha )$ denote the class of all univalent functions $f$ in the unit disk $\mathbb{D}$ and is given by $f(z)=z+a_2{z}^2+a_3{z}^3+\cdots$, satis…
