Abstract
In this paper, we introduce and examine a certain subclass of analytic and bi-univalent functions defined on the open unit disk of the complex plane, subordinated to the improved q–exponential function. We provide coefficient bounds for the initial coefficients of the functions belonging to the defined class, and solve the Fekete–Szego˝ problem for the proposed class.
