Excluding a large theta graph

Guoli Ding, Emily Marshall

A theta graph, denoted $θ_{a, b, c}$ , is a graph of order $a + b + c - 1$ consisting of a pair of vertices and three independent paths between them of lengths $a$ , $b$ , and $c$ . We provide…

Characterizing binary matroids with no $P_{9}$ -minor

Guoli Ding, Haidong Wu

In this paper, we give a complete characterization of binary matroids with no $P_{9}$ -minor. A 3-connected binary matroid $M$ has no $P_{9}$ -minor if and only if $M$ is one of the inte…
