Geometric and approximation properties of a complex Post-Widder operator in the unit disk
Abstract
The purpose of this work is to obtain Jackson-type estimates in approximation by a complex Post-Widder operator in the unit disk. In addition, these operators preserve some sufficient conditions for starlikeness and univalence of analytic functions. © 2005 Elsevier Ltd. All rights reserved.
