Sharp Bounds of the Fekete–Szegö Problem and Second Hankel Determinant for Certain Bi-Univalent Functions Defined by a Novel <i>q</i>-Differential Operator Associated with <i>q</i>-Limaçon Domain

In this present paper, we define a new operator in conjugation with the basic (or <i>q</i>-) calculus. We then make use of this newly defined operator and define a new class of analytic and bi-univalent functions associated with the <i>q</i>-derivative operator. Furthermore,...
