Abstract
In this paper, we consider a new class CS * s,b of generalized close-to-starlike functions, which is defined by means of the Srivastava-Attiya operator J s,b involving the Hurwitz-Lerch Zeta function Φ(z, s, a). Basic results such as inclusion relations, coefficient inequalities and other interesting properties of this class are investigated. Relevant connections of some of the results presented here with those that were obtained in earlier investigations are pointed out briefly.
