Title: Dressian and metric tree arrangements.
Abstract - We give an introduction to the study of the Dressian
Dr(k,n), a tropical prevariety that is an outer approximation to the
tropical Grassmannian. We will discuss the various structures that
this space is endowed with, specifically the relation to metric tree
arrangements in Dr(3,n). If time permits, we can discuss various
generalizations and applications.
