Certifying Non-representability of Matroids Over Prime Fields
Jim Geelen, Geoff Whittle
It is proved that, for a prime number , showing that an -element matroid is not representable over requires only rank evaluations.

Inequivalent Representations of Matroids over Prime Fields
Jim Geelen, Geoff Whittle
It is proved that for each prime field , there is an integer such that a 4-connected matroid has at most inequivalent representations over . We also pro…

The internally 4-connected binary matroids with no M(K3,3)-minor
Dillon Mayhew, Gordon Royle, Geoff Whittle
We give a characterization of the internally 4-connected binary matroids that have no minor isomorphic to M(K3,3). Any such matroid is either cographic, or is isomorphic to a parti…
