关于$\ell^\infty(3)$中的严格太阳
On strict suns in $\ell^\infty(3)$
摘要:
赋范线性空间X的子集M称为{ \it严格太阳},如果对于每个点$x\in X\setminus M$,其离~ $M$最近的点的集合非空,并且如果$y\in M$是从M到x的最近点,则y是从M到射线$\{λx+(1- λ)y | λ>0\}$的所有点的最近点。本文给出了严格太阳在$\ell^\infty(3)$中的几何特征。
英文摘要:
A subset M of a normed linear space X is said to be a {\it strict sun} if, for every point $x\in X\setminus M$, the set of its nearest points from~$M$ is non-empty and if $y\in M$ is a nearest point from M to x, then y is a nearest point from M to all points from the ray $\{λx+(1- λ)y | λ>0\}$. In the paper there obtained a geometrical characterisation of strict suns in $\ell^\infty(3)$.
