Seminar on Algebra, Geometry and Physics The Gelfand--Zetlin integrable system is defined by the set of
generalized eigenvalues of hermitian matrices. I will construct a
"tropical analog" of this set using the combinatorics of some weighted
planar graphs. The same methods can be used to give a description of the
Horn inequalities on the eigenvalues of sums of hermitian matrices.
