摘要

主要研究了非对称赋范空间上的最远点问题.首先,在非对称赋范空间中引入了最远点及最远点映射的概念,研究了最远点集及最远点映射的基本性质;其次,借助非对称赋范空间对偶空间理论得到了点到非空有界集的最大距离公式;最后,利用拟支撑超平面理论给出了点到非空有界集的最远点的等价刻画.

Abstract

This paper mainly studies the farthest point problem in asymmetric normed space.Firstly,the concepts of the farthest point and the farthest point mapping were introduced in the asymmetric normed space,and the ba-sic properties of the farthest point set and the farthest point mapping were investigated.Secondly,the maximum distance formula from point to non-empty bounded set was derived by means of the dual space theory of asym-metric normed space.Finally,by using the quasi-supported hyperplane,the farthest point from a point to a non-empty bounded set was characterized.
