Matroids and wilder things: Polymatroids and Delta-matroids

Abstract:  Matroids will be introduced in this talk. I will give an example of a result for general matroids, which has interesting corollaries in more specialized classes of structures, like graphs. I will also discuss two generalizations of matroids. In polymatroids, I will give a conjecture from Vertigan, that, if true, has an important corollary in matroid theory. That is, it gives us Rota's conjecture. In delta-matroids, I will present a splitter theorem.
