The structure of delta-matroids with width one twists
Carolyn Chun, Rhiannon Hall, Criel Merino +2
The width of a delta-matroid is the difference in size between a maximal and minimal feasible set. We give a Rough Structure Theorem for delta-matroids that admit a twist of width…

On zeros of the characteristic polynomial of matroids of bounded tree-width
Carolyn Chun, Rhiannon Hall, Criel Merino +1
We develop some basic tools to work with representable matroids of bounded tree-width and use them to prove that, for any prime power and constant , the characteristic polyn…

Inductive tools for connected ribbon graphs, delta-matroids and multimatroids
Carolyn Chun, Deborah Chun, Steven D. Noble
We prove a splitter theorem for tight multimatroids, generalizing the corresponding result for matroids, obtained independently by Brylawski and Seymour. Further corollaries give s…
