摘要
设D是复平面上的Jordan区域,证明了设D的边界是某些光滑的,又f∈B(D),则在Fejer点上f(z)的Hermite—Fejer插值多项式在D上一致收敛。
Let D be Jordan domain in the complex plane,D=Γ.What follows are proved:Suppose that Γ satisfies some smooth conditions and f∈B(D),then Hermite—Fejer lnterpolation polynomials of f(z) based on Fejer points converge uniformly on closed domain D.
