摘要本文引进一类q-Durrmeyer-Stancu算子,并研究该算子列的一些统计逼近性质。得到算子列的统计逼近定理,同时借助连续模和Lipschitz函数类给出算子列统计收敛速度的估计。 In this paper, a kind of q-Durrmeyer-Stancu operators is introduced. Some statistical approximation properties of these operators are studied. The statistical approximation theorem of these operators is given. The estimates of the rate of statistical convergence for these operators are also investigated by means of modulus of continuity and the help of functions of the Lipschitz class.
