分析了加法幂等交换半环上的伴随矩阵,获得了伴随矩阵的若干性质,给出伴随矩阵的积和式的一个不等式.同时讨论了矩阵与其伴随矩阵乘积的幂等性.
In this paper, adjoint matrices over a commutative additively idempotent semiring are approached. Some properties of adjoint matrices are given and an ineq - uality for the permanent of adjoint matrix of a matrix is obtained. Also, idempotence of the product of a matrix and its adjoint matrix is discussed.
