中文摘要: |
该文研究Bernstein多项式的绝对收敛性.证明了,对每个x∈[0,1],一个有界变差函数的Bernstein多项式序列是绝对|C,1|可和的,而且给出了Berstein多项式序列的绝对|C,1|和式的余项的估计. |
英文摘要: |
This note is devoted to the study of the absolute convergence of Bernstein polynomials. It is proved that for each x∈[0,1], the sequence of the Bernstein polynomials of a function of bounded variation is absolutely summable by |C,1| method. Moreover, the estimate of the remainders of the |C,1| sum of the sequence of the Bernstein polynomials is obtained. |
