Packing Steiner Trees

Matt DeVos, Jessica McDonald, Irene Pivotto

Let $T$ be a distinguished subset of vertices in a graph $G$ . A $T$ -\emph{Steiner tree} is a subgraph of $G$ that is a tree and that spans $T$ . Kriesell conjectured that $G$ contai…

Maximum size binary matroids with no AG(3,2)-minor are graphic

Joseph P. S. Kung, Dillon Mayhew, Irene Pivotto +1

We prove that the maximum size of a simple binary matroid of rank $r \geq 5$ with no AG(3,2)-minor is $(2 r + 1)$ and characterise those matroids achieving this bound. When $r…
