Abstract

In this paper, we introduce and investigate a new subclass of Bi-univalent functions defined in the open unit disk, associated with Chebyshev polynomials by applying $q$-derivative operator. Furthermore, We find estimates for the general Taylor-Maclaurin coefficients of the functions in this class and also we obtain an estimation for Fekete-Szeg$\ddot{o}$ problem for this class.

Keywords and Phrases

Analytic functions, Univalent and Bi-univalent functions, Fekete-Szeg$\ddot{o}$ inequality, Chebyshev polynomials and $q$-derivative operator.

A.M.S. subject classification
