Plats: KTH, F11

Abstract: Matroids are a combinatorial generalization of both graphs and
finite point configurations in vector spaces. The later are called
representable matroids. Matroids which are equipped with an additional
valuation are called valuated matroids or tropical linear spaces. They
are an object of central interest in tropical geometry.
I will introduce these matroids and their moduli spaces, the Dressians
and tropical Grassmannians.
Moreover, I will discuss recent results about their polyhedral structure.
