There is a well-established tradition of geometric methods in
combinatorial representation theory (Gelfand, Zelevinsky, Littelman, Pak, etc).
In this talk we follow this and we discuss a counterexample to a conjecture of Berenstein
and Kirillov on Kostka numbers and Gelfand-Tsetlin patterns. This is joint work with Tyrrell McAllister.
