Cylindrical Networks and Total Nonnegativity

Robert Angarone

We prove that an infinite block-Toeplitz matrix with finite diagonal support is totally nonnegative if and only if it is the weight matrix of a cylindrical network. This generalize…

Chow Rings of Matroids as Permutation Representations

Robert Angarone, Anastasia Nathanson, Victor Reiner

Given a matroid and a group of its matroid automorphisms, we study the induced group action on the Chow ring of the matroid. This turns out to always be a permutation action. Work…
