关于齐次线性方程组AX=0 (Rank A≥n-2)的半正解

On Semi-positive Solution of Homogeneoug Linear Equations AX=0 (Rank A≥n-2)

线性方程组的解称为半正的,如果本文讨论了当Rank(A)≥n-2时,齐次线性方程组AmxnX=O有半正解的条件,在有半正解的情况下,给出半正通解。

A solution α= (α1……αn)of linear equations AX=0 is called semi-positive if both i, αi≥ 0 and i, αi>0 are satisfied.This paper discusses conditions that homogeneous linear eouations AX=0 with Rank A≥n-2 has semi-positive solution and obtain the semi-positive general solution (if axist).
