Hypercubes and Hamilton cycles of display sets of rooted phylogenetic networks
Janosch Döcker, Simone Linz, Charles Semple
In the context of reconstructing phylogenetic networks from a collection of phylogenetic trees, several characterisations and subsequently algorithms have been established to recon…
A splitter theorem for elastic elements in -connected matroids
George Drummond, Charles Semple
An element of a -connected matroid is elastic if , the simplification of , and , the cosimplification of , ar…
The excluded minors for 2- and 3-regular matroids
Nick Brettell, James Oxley, Charles Semple +1
The class of 2-regular matroids is a natural generalisation of regular and near-regular matroids. We prove an excluded-minor characterisation for the class of 2-regular matroids. T…
Excluded minors are almost fragile II: essential elements
Nick Brettell, James Oxley, Charles Semple +1
Let be an excluded minor for the class of -representable matroids for some partial field , let be a -connected strong -stabilizer tha…
