Graphs whose flow polynomials have only integral roots
Joseph P. S. Kung, Gordon F. Royle
We show if the flow polynomial of a bridgeless graph G has only integral roots, then G is the dual graph to a planar chordal graph. We also show that for 3-connected cubic graphs,…

The internally 4-connected binary matroids with no M(K3,3)-minor
Dillon Mayhew, Gordon Royle, Geoff Whittle
We give a characterization of the internally 4-connected binary matroids that have no minor isomorphic to M(K3,3). Any such matroid is either cographic, or is isomorphic to a parti…
