摘要
There have been many elegant results discussing the approximation proper- ties of the Bieberbach polynomials. However, very few papers investigated the approxi- mation properties of the extremal polynomials over Jordan curves. In the present paper, some results on a class of extremal polynomials over C1+αsmooth Jordan curves are obtained.
关于Bieberbach多项式的逼近性质已有许多精彩结果,然而Jordan曲线上极值多项式的逼近性质却很少被考察.本文得到了 C1+α光滑 Jordan曲线上一类极值多项式的一些逼近结果.
