چکیده
We prove existence of quasi-periodic solutions with two frequencies of completely resonant, periodically forced nonlinear wave equations with periodic spatial boundary conditions. We consider both the cases the forcing frequency is: (Case A) a rational number and (Case B) an irrational number.

QUASI-PERIODIC SOLUTIONS OF THE EQUATION vtt − vxx + v 3 = f(v)
We consider 1D completely resonant nonlinear wave equations of the type vtt − vxx = −v +O(v) with spatial periodic boundary conditions. We prove the existence of a new type of quasi-periodic small amplitude solutions with two frequencies, for more general nonlinearities. These solutions turn out to be, at the first order, the superposition of a traveling wave and a modulation of long period, de...
متن کاملComplete classification of discrete resonant Rossby/drift wave triads on periodic domains
We consider the set of Diophantine equations that arise in the context of the partial differential equation called “barotropic vorticity equation” on periodic domains, when nonlinear wave interactions are studied to leading order in the amplitudes. The solutions to this set of Diophantine equations are of interest in atmosphere (Rossby waves) and Tokamak plasmas (drift waves), because they prov...
متن کاملNear-Resonant Steady Mode Interaction: Periodic, Quasi-periodic, and Localized Patterns
Motivated by the rich variety of complex periodic and quasi-periodic patterns found in systems such as two-frequency forced Faraday waves, we study the interaction of two spatially periodic modes that are nearly resonant. Within the framework of two coupled one-dimensional Ginzburg-Landau equations we investigate analytically the stability of the periodic solutions to general perturbations, inc...
متن کاملEquilibrium Quasi-periodic Configurations with Resonant Frequencies in Quasi-periodic Media Ii: Kam Theory
We develop an a-posteriori KAM theory for the equilibrium equations for quasi-periodic solutions in a quasi-periodic Frenkel-Kontorova model when the frequency of the solutions resonates with the frequencies of the substratum. The KAM theory we develop is very different both in the methods and in the conclusions from the more customary KAM theory for Hamiltonian systems or from the KAM theory i...
متن کاملEquilibrium Quasi-periodic Configurations with Resonant Frequencies in Quasi-periodic Media I: Perturbative Expansions
We consider 1-D quasi-periodic Frenkel-Kontorova models (describing, for example, deposition of materials in a quasi-periodic substratum). We study the existence of equilibria whose frequency (i.e. the inverse of the density of deposited material) is resonant with the frequencies of the substratum. We study perturbation theory for small potential. We show that there are perturbative expansions ...
