摘要
讨论了 Meyer-Knig and Zeller算子的保形逼近问题 ,我们用基于算子特殊结构的分析方法得到了该算子的保单调性 .保凸性以及保形逆定理等保形性质 .
In this paper, properties of shape preserving for Meyer-Konig and Zeller Operators are considered, of which the monotonicity and convexity preserving as well as the inverse theorem of shape preserving are obtained by analytical method clopend on the special construct of the operators.
