HANKEL DETERMINANT FOR CERTAIN SUBCLASS OF ANALYTIC FUNCTIONS ASSOIATED WITH GENERALIZED SRIVASTAVA–ATTIYA OPERATOR

Abstract

This paper is to introduce a certain class of analytic functions denoted by b s ( )  which is defined by generalized Srivastava – Attiya operator. This operator is associated with Hurwitz-Lerch Zeta function, obtain an upper bound to the second Hankel determinant |𝑎2 𝑎4 − 𝑎3 2 | for the class b s ( )  .
