Inverse eigenvalue and related problems for hollow matrices described by graphs
F. Scott Dahlgren, Zachary Gershkoff, Leslie Hogben +2
A hollow matrix described by a graph is a real symmetric matrix having all diagonal entries equal to zero and with the off-diagonal entries governed by the adjacencies in .…

Elastic elements in 3-connected matroids
George Drummond, Zachary Gershkoff, Susan Jowett +2
It follows by Bixby's Lemma that if is an element of a -connected matroid , then either ${\rm co}(M\delete e)$, the cosimplification of $M\delete e$, or ,…

Characterization and enumeration of 3-regular permutation graphs
Aysel Erey, Zachary Gershkoff, Amanda Lohss +1
A permutation graph is a graph that can be derived from a permutation, where the vertices correspond to letters of the permutation, and the edges represent inversions. We provide a…
