Abstract:- The zero-term rank of a matrix is the maximum number of zeros in any generalized diagonal. This article characterizes the linear operators that preserve zero-term rank of m n ´ atrices when the matrices have entries either in a field with at least mn+1 elements or in a ring whose characteristic is not 2. Key-Words:- Zero-term rank, term rank, linear operator, preserver, ( , ,)P Q B-operator, cell.
In this article, we introduce another standard form of linear preservers. This new standard form pro...
