Özet
By using a univalent and analytic function τ in a suitable open disk centered in origin, we attach to analytic functions f, the complex Bernsteintype operators of the form Bn,q τ (f) = Bn,q (f ο τ-1) ο τ, where Bn,q denote the classical complex q-Bernstein polynomials, q ≥ 1. The new complex operators satisfy the same quantitative estimates as Bn,q. As applications, for two concrete choices of τ, we construct complex rational functions and complex trigonometric polynomials which approximate f with a geometric rate.
