On the existence of asymptotically good linear codes in minor-closed classes

Peter Nelson, Stefan H. M. van Zwam

Let $C = (C_{1}, C_{2}, \dots)$ be a sequence of codes such that each $C_{i}$ is a linear $[n_{i}, k_{i}, d_{i}]$ -code over some fixed finite field $F$ , where $n_{i}$ is the le…

The structure of graphs with a vital linkage of order 2

Dillon Mayhew, Geoff Whittle, Stefan H. M. van Zwam

A linkage of order k of a graph G is a subgraph with k components, each of which is a path. A linkage is vital if it spans all vertices, and no other linkage connects the same pair…

Stability, fragility, and Rota's Conjecture

Dillon Mayhew, Geoff Whittle, Stefan H. M. van Zwam

Fix a matroid N. A matroid M is N-fragile if, for each element e of M, at least one of M\e and M/e has no N-minor. The Bounded Canopy Conjecture is that all GF(q)-representable mat…
