Sulle matrici torneo associate a matrici di permutazione


Abstract


A tournament matrix A is associated with a permutation matrix P if AP is still a tournament matrix.In this paper we consider the problem of the existence and the construction of such matrices and in particular we prove that A of order n is associated with a n-cycle P if and only if AP=A<sub>T</sub>.In that case the tournament with A is rotational and the eigenvalues of A are determined.
