摘要: 对于n×n 阶矩阵A和B,若矩阵AB和BA都为零矩阵,则称A和B正交。若A2为零矩阵,则称A为自正交。本文研究一类特殊tropical(0,-1)矩阵的正交性以及二元布尔代数和链半环上矩阵的自正交性。研究二元布尔代数上矩阵的自正交性,间接刻画二元布尔代数上的零方矩阵形式。

关键词: Tropical 代数, 正交性, 二元布尔代数, 链半环

Abstract: For n×n matrices A and B, they are considered orthogonal when both AB and BA are zero matrices, and A is deemed self-orthogonal when A2 is a zero matrix. The orthogonality of a specific class of tropical(0,-1)matrices, as well as the self-orthogonality of matrices on binary Boolean algebras and chain semirings is studied. The self-orthogonality of matrices on binary Boolean algebras are studied and the zero-square matrix form on those algebras is ndirectly characterized.

Key words: tropical algebra, orthogonality, binary Boolean algebra, chain semiring
