Toric degenerations of flag varieties and their applications

Toric degenerations translate geometric properties of varieties to combinatorial ones of polytopes or polyhedral cones. In this talk I will introduce a general framework to construct toric degenerations of flag varieties via birational sequences and Newton-Okounkov bodies. Most of the known toric degenerations turn out to be concrete examples of this construction. As an application, I will explain how to get the exact value of the Gromov width of a coadjoint orbit.
