Classes of matrices associated with the optimal assignment problem
The paper is a continuation of the study of matrices having as elements integer powers of a rational indeterminate and their relation with the optimal assignment problem begun in \textit{H. J. Ryser}, A new look at the optimal assignment problem, Linear Algebra Appl. 66, 113-121 (1985; Zbl 0563.15013).
