Estimates on coefficients of a general subclass of bi-univalent functions associated with symmetric \(q\)-derivative operator by means of the Chebyshev polynomials
Summary: In this paper, we study a newly-constructed subclass of bi-univalent functions defined by using symmetric \(q\)-derivative operator. Upper bounds for the second and third coefficients, and also Fekete-Szegö inequalities of functions in this subclass are founded. Moreover, certain special cases are also indicated.
