Hermite-Fejer插值于L_p下的收敛逼近阶

An Upper Bound for the Rate of Mean Convergence of the Hermite-Fejer Process

本文把文［1—3」等仅对P≤4给予证明的P．Erdos－Feldheim型定理给出了一个完整的证明，且把文［1］的结果作了改进．

Papers [1-3] give 'P Erdos and E Feldheim' type theorem for some interpolatory processes, but its proof is only for p ≤ 4. This paper gives a complete proof and obtains a better result than paper [1].
