摘要

与传统的信息不等式方法不同，本文利用熵函数区域Γn*及其闭包* Γn*的外界多拟面区域Γn的极值射线来表征熵函数区域。研究了Γ3*的性质和Γn作为* *的外界的严密性。

Characterizing the entropy function region via extreme rays

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