Abstract
In this paper, by making use of $ q$-derivative, we define a new subclass of analytic and bi-univalent functions related to Horadam polynomials. For functions belonging to this class, we derive coefficient inequalities and the Fekete-Szeg$\ddot{o}$ inequalities. We also provide relevant connections of our results with those considered in earlier investigations.
