Coefficient estimates and Fekete–Szegö inequalities for a families of bi- functions related to q-Srivastava–Attiya operator

In this paper, by making use of [Formula: see text]-Srivastava–Attiya operator, we define a certain families of holomorphic and bi-univalent functions [Formula: see text] and [Formula: see text] which defined in the unit disk [Formula: see text]. The initial coefficient estimates [Formula: see text] and [Formula: see text] on the certain families are obtained. Also, we investigate Fekete–Szegö-type inequalities for these families. Further, we point out several certain special cases for our results.
