Column ranks and their preservers of general Boolean matrices
Seok-Zun Song and Sang-Gu Lee
Cheju National University and Sung Kyun Kwan University
We show the extent of the difference between semiring rank and column rank of matrices over finite Boolean algebra. We also obtain the characterizations of linear operators that preserve column ranks of general Boolean matrices.
Keywords: Boolean column rank, linear operator
MSC numbers: Primary 15A03, 15A04
