Bi-Bazilevič functions of complex order involving Ruscheweyh type q-difference operator

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2018
In this paper, we define a new subclass of bi-univalent functions involving q-difference operator in the open unit disk. For functions belonging to this class, we obtain estimates on the first two Taylor-Maclaurin coefficients |a2| and |a3|.
