摘要
研究Sikkema-Kantorovirch算子在L~p空间的逼近问题,给出了它的强型正定理和弱型逆定理,从而得到其逼近的特征刻划。
ln this paper, the problems of approximation for Sikkema-Kantorovitch operators in Lp space are studied, and the strong-type direct theorem and weak-type inverse theorem of the approximation are given, thus its approximation characterization is obtained .
