Rigorous Derivation of the Wave Kinetic Equation for full -FPUT System
Katja Vassilev, Boyang Wu
The Fermi--Pasta--Ulam--Tsingou (FPUT) system, describing the evolution of coupled harmonic oscillators, has been the subject of much attention since the 1950's when experiment…

Rigorous Derivation of the Wave Kinetic Equation for -FPUT System
Boyang Wu
Wave kinetic theory has been suggested as a way to understand the longtime statistical behavior of the Fermi-Pasta-Ulam-Tsingou (FPUT) system, with the aim of determining the therm…
