MAXIMAL COLUMN RANK PRESERVERS OF INTEGER MATRICES
Song, Seok-Zun; Kang, Kyung-Tae;

Abstract
The maximal column rank of an $\small{m{\times}n}$ matrix A over the ring of integers, is the maximal number of the columns of A that are weakly independent. We characterize the linear operators that preserve the maximal column ranks of integer matrices.
