摘要
借助K-泛函、广义Minkowski不等式、极大函数的定义及其性质,给出修正二元Gauss-Weierstrass算子线性组合在L_(p)(R^(2)+)空间中的逼近定理,并对此定理进行了证明.
The purpose of adding linear combinations to positive linear operators is to improve the approximation order.The binary Gauss-Weierstrass operator belongs to this kind of positive linear operator.In this paper,by means of K-functional,generalized Minkowski inequality,definition and properties of maximal function,the approximation theorem of linear combination of modified binary Gauss-Weierstrass operator in L_(p)(R^(2)+)space is given and proved.
