Certain geometric properties of normalized and generalized Hurwitz–Lerch Zeta functions
摘要
The purpose of this paper is to establish a set of sufficient conditions under which the normalized form of the generalized Hurwitz–Lerch Zeta functions possesses certain geometric properties, including close-to-convexity, univalency, convexity, and starlikeness in the open unit disk. The relevance of the obtained results with some known results in the literature is also discussed.
