Linear Operators that Preserve Qualitative Matrix Structures
We characterized the group of linear operators that preserve sign-nonsingular matrices over ��(ℝ). Then we extended these results to n show that a linear operator T that strongly preserves L-matrices over ��,�(ℝ) if and only if T preserves L-matrices and T is also one to one on m,n the set of cells....
