On minor-closed classes of matroids

Abstract:

Over the last 10 years I have been working with Bert Gerards and Geoff Whittle on trying to extend the graph minors project of Neil Robertson and Paul Seymour to matroids representable over a given finite fields. Most of the work involves finding structural descriptions of matroids in a minor-closed class. I will present recent work that is particular to matroids representable over fields of non-prime order.
