Compact Simultaneous Approximation in Bsanacn spaces
摘要/Abstract
摘要:
主要研究Banach空间中有限个紧集的同时逼近问题,从一般情况定义同时逼近的形式,利用已知的一致范数连续空间的结论,给出了同时逼近的特征定理,以及几种特殊情况的结论.
Abstract:
The best approximation to a finite number of compact sets simultaneously are considered.For a general form,the characteristic and some results about several special cases of the best proximation are derived in a changed form,and the known results on continuous space is used in process of the theorem.
