摘要
本文给出了Kantorovich算子在一致逼近意义下的加权同时逼近的正定理及非最优逼近阶的特征刻划。
The aim of this present paper is to prove the direct results and characterization on weighted simultaneous approximation by Kantorovich operators in uniform approximation making use of the weighted moduli of smoothness and K-functional as following:Let f∈C〔0,1〕and F<sup>2r</sup>∈C〔0,1〕,then we have
