Excluded minors for the class of split matroids
- Amanda Cameron (MPI MiS, Leipzig)
The class of split matroids arises by putting conditions on the system of split hyperplanes of the matroid base polytope. It can alternatively be defined in terms of structural properties of the matroid. We use this structural description to give an excluded minor characterisation of the class. A small introduction to matroid theory will be given before motivating and explaining the result.
