构造了一类推广的Bernstein—Kantorovich算子,利用Cauchy不等式、Jensen不等式和Hardy-Little—wood极大函数等工具,研究了该算子在Orlicz空间内的逼近问题,得出了逼近阶的两种估计.
In this paper,a kind of generalized Bernstein-Kantorovich operators were introduced and the approximation problems of these operators studied in Orlicz spaces by using Cauchy inequality, Jensen inequality and Hardy-Littlewood maximal function,and the approximation degree of two kind of estimates was obtained.
