The $G$ -invariant and catenary data of a matroid

Joseph E. Bonin, Joseph P. S. Kung

The catenary data of a matroid $M$ of rank $r$ on $n$ elements is the vector $(ν (M; a_{0}, a_{1}, \dots, a_{r}))$ , indexed by compositions $(a_{0}, a_{1}, \dots, a_{r})$ , where $a_{0} \geq 0$ ,\, $a_i…

Lattices related to extensions of presentations of transversal matroids

Joseph E. Bonin

For a presentation $A$ of a transversal matroid $M$ , we study the set $T_{A}$ of single-element transversal extensions of $M$ that have presentations that exten…

An infinite family of excluded minors for strong base-orderability

Joseph E. Bonin, Thomas J. Savitsky

We discuss a conjecture of Ingleton on excluded minors for base-orderability, and, extending a result he stated, we prove that infinitely many of the matroids that he identified ar…
