The extreme rays of the 5 x 5 copositive cone
Résumé
We give an explicit characterization of all extreme rays of the cone C_5 of 5×5 copositive matrices. We show that the extreme rays which are not positive semi-definite or nonnegative form a 10-dimensional variety, which can be parameterized in a semi-trigonometric way.
