线性方程组有全非零解的几个充要条件的讨论

Discussion on the several Sufficient and Necessary Conditions of Linear Equations having All-nonzero Solution

本文对文献中关于线性方程组有全非零解的充要条件进行了分析,指出了它们在本质上的统一,并简化了部分条件。

This paper analyses several sufficient and necessary conditions in existing papers, on the problem of linear equations having all- nonzero solution, indicates their unity in nature, and simplifies part conditions.
