Korteweg-de Vries and Fermi-Pasta-Ulam-Tsingou: asymptotic integrability of quasi unidirectional waves
Matteo Gallone, Antonio Ponno, Bob Rink
In this paper we construct a higher order expansion of the manifold of quasi unidirectional waves in the Fermi-Pasta-Ulam (FPU) chain. We also approximate the dynamics on this mani…

Adiabatic invariants for the FPUT and Toda chain in the thermodynamic limit
T. Grava, A. Maspero, G. Mazzuca +1
We consider the Fermi-Pasta-Ulam-Tsingou (FPUT) chain composed by particles and periodic boundary conditions, and endow the phase space with the Gibbs measure at small te…
