Starlikeness properties of a new integral operator for meromorphic functions. (English) Zbl 1223.30005

Summary: We define here an integral operator \(\mathcal H_{\gamma_{1},\dots,\gamma_{n}}\) for meromorphic functions in the punctured open unit disk. Several starlikeness conditions for the integral operator \(\mathcal H_{\gamma_{1},\dots,\gamma_{n}}\) are derived.
