Grünwald插值算子的加权L1收敛速度

Rate of Weighted L_1 Convergence of the Grünwald (Interpolatory) Operators

给出了以第一类Chebyshev多项式的零点为插值结点组的Grünwald插值多项式在加权L1下收敛速度的一个估计.

We obtained an upper bounded for the weighted L_1 convergence rate of the Grünwald (interpolatory) polynomials based on the zeros of Chebyshev polynomials of the first kind.
