热带矩阵秩之间的分离

A separation between tropical matrix ranks

Yaroslav Shitov

摘要:

我们继续研究热带矩阵的秩函数。在本文中,我们解释了如何减少计算秩矩阵的“超热带半场”的标准热带的情况下。利用计数的方法,我们证明了一个$01$ -矩阵的存在性,该矩阵具有多个1且不具有大的全1子矩阵,并且我们将这些结果结合起来,构造了一个具有热带秩$o(n^{0.5+\varepsilon})$和Kapranov秩$n-o(n)$的$n\times n$矩阵.

英文摘要:

We continue to study the rank functions of tropical matrices. In this paper, we explain how to reduce the computation of ranks for matrices over the `supertropical semifield' to the standard tropical case. Using a counting approach, we prove the existence of a $01$-matrix with many ones and without large all-one submatrices, and we put our results together and construct an $n\times n$ matrix with tropical rank $o(n^{0.5+\varepsilon})$ and Kapranov rank $n-o(n)$.
