We introduce the notion of the slot length of a family of matrices over an arbitrary field ${\mathbb {F}}$ . Using this definition it is shown that, if $n\ge 5$ and A and B are $n\times n$ complex matrices with A unicellular and the pair $\{A,B\}$ irreducible, the slot length s of $\{A,B\}$ satisfies $2\le s\le n-1$ , where both inequalities are sharp, for every n . It is conjectured that the slot length of any irreducible pair of $n\times n$ matrices, where $n\ge 5$ , is at most $n-1$ . The slot length of a family of rank-one complex matrices can be equal to n .

矩阵族的时隙长度
我们引入的概念槽长 任意域上的矩阵族${\mathbb {F}}$ . 使用这个定义表明,如果$n\ge 5$ 和一种 和乙 是$n\次 n$ 复杂矩阵一种 单细胞和对$\{A,B\}$ 不可约,槽长s 的$\{A,B\}$ 满足$2\le s\le n-1$ ,其中两个不等式都很尖锐,对于每个n . 推测任何不可约对的槽长$n\次 n$ 矩阵,其中$n\ge 5$ , 最多为$n-1$ . 秩一复矩阵族的槽长度可以等于n .
