Original Research Paper


In this investigation, we propose to make use of the Horadam polynomials and introduce two classes of bi-univalent functions. For functions belonging to these classes, the coefficient inequalities and the Fekete–Szegö inequalities are discussed. Some interesting remarks of the results presented here are also investigated.
