Certain properties of the Dziok--Srivastava operator. (English) Zbl 1081.30021
Making use of Hadamard product (or convolution), a certain linear operator $H_{p,q,s}(\alpha _1)$ was recently introduced and studied in a series of papers by Dziok and Srivastava. In this paper, some other properties of the operator $H_{p,q,s}(\alpha _1)$ are derived with the help of differential subordination.
