Matroidal Entropy Functions: A Quartet of Theories of Information, Matroid, Design, and Coding

open access: yesEntropy, 2021
In this paper, we study the entropy functions on extreme rays of the polymatroidal region which contain a matroid, i.e., matroidal entropy functions. We introduce variable strength orthogonal arrays indexed by a connected matroid M and positive integer v
