The zero-term rank of a matrix is the maximum number of zeros in any generalized diagonal. This article characterrizes the linear operators that preserve zero-term rank of m × n matrices when the matrices have entries either in a field with at least mn +2 elements or in a ring whose characteristic is not 2.
