摘要
本文首先引进关于最佳同时L_P逼近的三种不同的提法,然后讨论了它们的各种性质。
In this paper, three different kinds of best simultaneous Lp-approximations are introdaced and their various properties, are discussed. We obtain the sufficient and necessary conditions to the existence of the elements of best simultaneous Lp-approximation. In addition, the representatives of the best simultaneous Lp-approximation values are given.
