Inequivalent representations of matroids
|Affiliation:||University of Waterloo|
|Room:||Mathematics & Computer Building (MC) 5158|
In joint work with Bert Gerards and Geoff Whittle, we showed that 4-connected matroids have a bounded number of inequivalent representations over fields of prime order. At the time we were confident that we could extend this to all finite fields. We were sadly mistaken.
