Quasi-Periodic solutions to Hamiltonian derivative wave $ d $ Systems with different tangential sites

Year: 2025

Type: article

Abstract: We use an abstract KAM (Kolmogorov-Arnold-Moser) theorem constructed by Berti-Biasco-Procesi[1] for Hamiltonian derivative wave equations to prove the existence of quasi-periodic solutions with different tangential sites to a class of coupled nonlinear Hamiltonian derivative wave $ d $ systems on $ \mathbb{T}. $
