DESCRIPTION:Andras Szenes\,University of Geneva\nWe describe a new approac
 h to classical eigenvalue inequalities for Hermitian matrices: the Gelfand
 -Zeitlin and the Horn inequalities. Taking a tropical limit\, these inequa
 lities are reproduced by certain piecewise linear functions on weighted pl
 anar networks.\nThis is joint work with A. Alekseev and M. Podkopaeva.
