Abstract
Positivity and atomicity are traditionally considered as basic conditions for direct methods. While the role of atomicity is well understood, the theoretical and practical consequences for a direct-methods procedure generated by the violation of the positivity criterion are not quite clear. Triplet and quartet relationships are analyzed in connection with the positivity Postulate.File in questo prodotto:
