论文摘要
通过将问题减少到有理的正交系统（Takeaka-Malmquist系统），该注释证明了使用假毛细血管距离在Hardy H2（D）空间中函数的N-最大理性近似。
Through reducing the problem to rational orthogonal system (Takenaka-Malmquist system), this note gives a proof for existence of n-best rational approximation to functions in the Hardy H2(D) space by using pseudohyperbolic distance.
