Abstract: In this study, we introduce and examine a subclasses of analytic and univalent functions defined by $q$-derivative. Here, we give necessary conditions for the functions to belong to these subclasses, and distortion bound and growth theorems for the functions belonging to these classes.
Keywords: Coefficient bound, convex function, $q$- derivative, quasi close-to-$q$ -convex function
