Girth in $GF(q)$-representable matroids

Combinatorics 2025-05-01 v1

Abstract

We prove a conjecture of Geelen, Gerards, and Whittle that for any finite field GF(q)GF(q) and any integer tt, every cosimple GF(q)GF(q)-representable matroid with sufficiently large girth contains either M(Kt)M(K_t) or M(Kt)M(K_t)^* as a minor.
