  • Abstract
    Contrary to the traditional method of information inequalities, in this paper, the entropy function region Γn* and its closure ̅Γn* are characterized via extreme rays of its outer bound polymatroidal region Γn. The characterization of Γ3* and the tightness of Γn as an outer bound on ̅Γn* are studied.
