Approximation by Complex Meyer-König and Zeller Operators

摘要

The Meyer-K ö nig and Zeller operator is one of the most challenging operators. Sometimes the study of its properties will rely on the weighted approximation by Baskakov operator. In this paper, this relation is extended to complex space; the quantitative estimates and the Voronovskaja type results for analytic functions by complex Meyer-K ö nig and Zeller operators were obtained.
