Matroids with a cyclic arrangement of circuits and cocircuits
Nick Brettell, Deborah Chun, Tara Fife +1
For all positive integers exceeding one, a matroid has the cyclic -property if its ground set has a cyclic ordering such that every set of consecutive elemen…
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…
Fan-extensions in fragile matroids
Carolyn Chun, Deborah Chun, Dillon Mayhew +1
If S is a set of matroids, then the matroid M is S-fragile if, for every element e in E(M), either M\e or M/e has no minor isomorphic to a member of S. Excluded-minor characterizat…
Computer-verification of the structure of some classes of fragile matroids
Carolyn Chun, Deborah Chun, Benjamin Clark +3
This technical report accompanies the following three papers. It contains the computations necessary to verify some of the results claimed in those papers. [1] Carolyn Chun, Debora…
