Grünwald插值于加权L_(p,w)下收敛阶估计

The rate of weighted L_p-convergence of the Grünwald process

给出了以第一类Chebyshev多项式的零点为插值结点组的Gr櫣nwald插值于加权Lp(权函数w(x)=(1-x2)-12)的收敛估计阶。推广了文[6]的结果。

The weighted L_p-convergence properities of the Grünwald process based on the second kind Chebyshev nodes are discussed. An accurate bound of its convergence rate is given.
