The excluded minors for lattice path polymatroids

Joseph Bonin, Carolyn Chun, Tara Fife

We find the excluded minors for the minor-closed class of lattice path polymatroids as a subclass of the minor-closed class of Boolean polymatroids. Like lattice path matroids and…

Matroids with different configurations and the same $G$ -invariant

Joseph E. Bonin

From the configuration of a matroid (which records the size and rank of the cyclic flats and the containments among them, but not the sets), one can compute several much-studied ma…

The free $m$ -cone of a matroid and its $G$ -invariant

Joseph E. Bonin, Kevin Long

For a matroid $M$ , its configuration determines its $G$ -invariant. Few examples are known of pairs of matroids with the same $G$ -invariant but different configu…
