The flag variety of tropical linear spaces
See the video of this talk.
Flag matroids are combinatorial abstractions of flags of linear subspaces, as matroids are of linear subspaces. In this talk, I will review several equivalent descriptions of the ordinary Dressian, which is a parameter space for tropical linear spaces. I will then introduce the flag Dressian as a tropical analogue of the partial flag variety. This work is joint with Madeline Brandt and Chris Eur.
