摘要
研究保持二元布尔半环上矩阵的传递闭包的线性算子,给出保持传递闭包的可逆线性算子的刻画,并证明当矩阵的阶n≥2时,强保持传递闭包的线性算子一定是可逆的。
The linear operators which preserve transitive closures of matrices over the binary Boolean semiring are studied, the characterizations of invertible linear operators which preserve transitive closures of matrices are given, and it is shown that the strong preservers are invertible when the order of the matrices n≥2.
