Resumo

In the present work, we define a subclass of uniformly starlike functions corresponding to the class of uniformly convex functions involving the q-analogue of a generalized differential operator. Furthermore, we discuss coefficient estimates, neighborhoods, partial sums, integral means inequality, and Radii of close-to-convexity and Starlikeness results related to the defined class.
