Coefficient estimates for families of bi-univalent functions defined by Ruscheweyh derivative operator

Serap Bulut, Abbas Kareem Wanas

The main purpose of this manuscript is to find upper bounds for the second and third Taylor-Maclaurin coefficients for two families of holomorphic and bi-univalent functions associated with Ruscheweyh derivative operator. Further, we point out certain special cases for our results.
