Abstract:
      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.
