Connectivity gaps among matroids with the same enumerative invariants

Joseph E. Bonin, Kevin Long

Many important enumerative invariants of a matroid can be obtained from its Tutte polynomial, and many more are determined by two stronger invariants, the $G$ -invariant a…

The excluded minors for three classes of 2-polymatroids having special types of natural matroids

Joseph E. Bonin, Kevin Long

If $C$ is a minor-closed class of matroids, the class $C^{'}$ of integer polymatroids whose natural matroids are in $C$ is also minor closed, as is the c…

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…
