Initial Bounds for a Subclass of Analytic and Bi-Univalent Functions Defined by Chebyshev Polynomials and q-Differential Operator

摘要

In this paper,we investigate the coefficient estimate and Fekete-Szeg(o) inequality of a subclass of analytic and bi-univalent functions defined by Chebyshev polynomials and q-differential operator.The results presented in this paper improve or generalize the recent works of other authors.
