局部有界函数的Baskakov-Bézier算子收敛阶新的估计

摘要

运用概率型算子的概率性质，研究了局部有界函数f的Baskakov-Bézier算子收敛阶的精确估计。其研究对于Bézier型算子逼近的研究工作，以及提高运用Bézier法的计算机辅助设计几何造型的精度的估计有重要意义。%By using the probabilistic property of probabilistic operator, the accurate estimation of Baskakov-Bézier oper-ator's rate of convergence for the locally bounded variation function is studied in this paper, which is important for the research of Bézier operator approximation and improving the accurate estimation of CAD geometic method model by using Bézier way.
