The Fekete–Szegö problem for a Ma–Minda type class of bi-univalent functions associated with the Hohlov operator

Abstract

In this paper, we solve Fekete–Szegö problem for a Ma–Minda type class [Formula: see text] of bi-univalent functions associated with the Hohlov operator which is a specialized case of the widely-investigated Dziok–Srivastava operator which, in turn, is contained in the Srivastava–Wright operator. Results for some of its consequent classes [Formula: see text] [Formula: see text] [Formula: see text] and [Formula: see text] are also given. A function [Formula: see text] in this class may satisfy one subordinate condition, whereas [Formula: see text], another. One result for that is also given by considering certain [Formula: see text]. Some useful consequences and relationships with some of the known results are also pointed out.
