Certain classes of analytic functions defined by Hurwitz–Lerch zeta function
Keyword(s):
Abstract In this work, we introduce and investigate a new class k - U S ~ s ( b , μ , γ , t ) {k-\widetilde{US}_{s}(b,\mu,\gamma,t)} of analytic functions in the open unit disk U with negative coefficients. The object of the present paper is to determine coefficient estimates, neighborhoods and partial sums for functions f belonging to this class.
