Generalized Coefficient Estimates for a New Subclass of Analytic Functions

Abstract

In this study, a new subclass of analytic functions in the open unit disk was defined with the help of the function obtained by applying the Salagean derivative to the q-Ruscheweyh derivative operator. For the functions belonging to this subclass, the coefficient bounds for the Fekete-Szeg & ouml; functional were determined. The results of this paper are a generalization of the results of Kanas and Darwish [Fekete-Szeg & ouml; problem for starlike and convex functions of complex order, Appl. Math. Lett. 23(7) (2010) 777-782].
