Partial Sums For Class Of Analytic Functions Defined By Integral Operator

Abstract

In the present paper, we study the class of analytic functions involving generalized integral operator, which is defined by means of a general Hurwitz Lerch Zeta function denoted by , ℑα s b f z( ) with negative coefficients. The aim of the paper is to obtain the coefficient estimates and also partial sums of its sequence , ℑα s b f z( ) . | Univalent functions | uniformly starlike functions | Hadamard product | partial sums | fractional derivatives and fractional integrals | ® 2012 Ibnu Sina Institute.
