We present an algebraic framework which simultaneously generalizes the notion of linear subspaces, matroids, valuated matroids, oriented matroids, and regular matroids. To do this,…

A counterexample to Montgomery's conjecture on dynamic colourings of regular graphs
Nathan Bowler, Joshua Erde, Florian Lehner +3
A \emph{dynamic colouring} of a graph is a proper colouring in which no neighbourhood of a non-leaf vertex is monochromatic. The \emph{dynamic colouring number} of a graph…
