摘要
给出了单纯形上两个相邻Bernstein多项式的差的一个估计式以及Bernstein多项式的一个渐近展开式并讨论了Bernstein多项式关于阶的高阶差分,得到一个极限公式。
This paper gives an estimation of error for the difference of two consecutive Bernstein polynomials defined on a simplex and gives an asymptotic expansion of Bernstein polynomial. Finally, the higher difference about the degree of Bernstein polynomials is discussed.
