Hydrodynamic equations for the classical Toda lattice
The Toda lattice is one of the most famous integrable system of classical mechanics. For N lattice sites there are $N+1$ conserved quantities. We are interested in the hydrodynamic scale, which means to start with suitably adjusted random initial data. In my talk I will outline the general structure and the resulting hydrodynamic Euler type equations. An unexpected connection to the repulsive log gas in one dimension is discussed.
