Matricial characterization of tournaments with maximum number of diamonds

Wiam Belkouche, Abderrahim Boussaïri, Soufiane Lakhlifi +1

A diamond is a $4$ -tournament which consists of a vertex dominating or dominated by a $3$ -cycle. Assuming the existence of skew-conference matrices, we give a complete characteriza…
