度量空间中的Borsuk问题

Borsuk's Problem in Metric Spaces

Jun Wang, Fei Xue, Chuanming Zong

摘要:

1933年,K. Borsuk提出了以下问题:能否将$\mathbb{E}^n$中的每一个有界集划分为直径更小的$n+1$子集?1965年,V.G.波强斯基和我。T. Gohberg提出了以下猜想:在$n$维度量空间中的每一个有界集都可以划分为直径更小的$2^n$子集。本文证明了如下结果:$n$维度量空间中的每一个有界集都可以划分为直径更小的$2^{n}((n+1)\log (n+1)+(n+1)\log \log (n+1)+5n+5)$子集。

英文摘要:

In 1933, K. Borsuk proposed the following problem: Can every bounded set in $\mathbb{E}^n$ be divided into $n+1$ subsets of smaller diameters? In 1965, V. G. Boltyanski and I. T. Gohberg made the following conjecture: Every bounded set in an $n$-dimensional metric space can be divided into $2^n$ subsets of smaller diameters. In this paper, we prove the following result: Every bounded set in an $n$-dimensional metric space can be divided into $2^{n}((n+1)\log (n+1)+(n+1)\log \log (n+1)+5n+5)$ subsets of smaller diameters.
