Linear operators that preserve zero-term rank of Boolean matrices

LeRoy. B. Beasley, Seok-Zun Song, and Sang-Gu Lee

Abstract

Go to

Zero-term rank of a matrix is the minimum number of lines (rows or columns) needed to cover all the zero entries of the given matrix. We characterize the linear operators that preserve zero-term rank of the $m \times n$ matrices over binary Boolean algebra.

Keywords: Boolean linear operator, term-rank, zero-term rank
