  • Abstract
    In this investigation we introduce, by making use of q−derivative operator, a new subclass which are an extension of some well-known subclasses of bi-univalent functions. Also, we give the upper bounds for the coefficients |a2| and |a3| for the functions belonging to this new subclass and its subclasses.
