The fifth-order partial differential equation for the description of the α+β Fermi-Pasta-Ulam model

Nikolay A. Kudryashov, Alexandr K. Volkov

We study a new nonlinear partial differential equation of the fifth order for the description of perturbations in the Fermi-Pasta-Ulam mass chain. This fifth-order equation is an e…
