Abstract

This paper deals with approximating properties and Voronovskaja-type results with quantitative estimates for complex genuine Durrmeyer-Stancu polynomials attached to analytic functions on compact disks. Some estimates on the rate of convergence are given. Also, the exact order of approximation is studied. (C) 2011 Elsevier Ltd. All rights reserved
