Sažetak
In this paper we obtain a quantitative estimate in the Voronovskaja's theorem and the exact orders in simultaneous approximation by the complex Lorentz polynomials attached to analytic functions in compact disks. Also, we study the approximation properties of the iterates of these polynomials.
