摘要
设L为一有界的分配格,以0和1分别表示L的最小元和最大元。本文给出L上的矩阵A=[a_(ij)]_■可逆的充分必要条件是它满足:■和■这简化了文中的条件,并且放宽了对格L的要求。
Let L be a bounded distributive lattice. The least element of L is denoted by 0 and the largest element by 1. In this paper, we give some invertible conditions for a matrix over the lattice L. Our conclusion is that a L-matrix A =[a_(ij)],x. is invertible if and only if the following conditions are satisfied: when i≠k. This result is a simplification of [1].
