best approximation

基本解释

In this paper the author introduces the definition of the best approximation in topological vector spaces by use of continuous linear functionals.
本文利用拓扑矢量空间中的连续线性泛函导入最佳逼近定义，给出了最佳逼近元的特征定理、存在性定理和唯一性定理。
As applications, several best approximation theorems and coincidence theorems involving discontinuous mappings and two different topological vector spaces are obtained.
作为应用，作者得到了几个涉及间断映象和两个不同拓扑矢量空间的最佳逼近定理和重合点定理。
The concept of L varisolvent family is introduced, some properties of it are given. Alternation theorems of best approximation and strong uniqueness theorems are proved.
给出L 变可解族的概念及若干性质，证明了最佳逼近元具有交错性，得到了广义有理逼近与具约束有理逼近的强唯一性定理。

Only one—the best approximation of an actual Schmidt was a man named Henry Noll—loaded anything close to forty-seven and a half tons in a single day, a rate that was, in any case, not sustainable.
