DESCRIPTION: Motivated by extreme value theory\, max-linear graphical model
 s have been recently introduced and studied as an alternative to the classi
 cal Gaussian or discrete distributions used in graphical modeling. We prese
 nt max-linear models naturally in the framework of tropical geometry. This 
 perspective allows us to shed light on some known results and to prove othe
 rs with algebraic techniques. In particular\, we rephrase parameter estimat
 ion for max-linear models in terms of cones in the tropical eigenspace fan.
  This is joint work with Claudia Klüppelberg\, Steffen Lauritzen and Ngoc T
 ran.
