Non-resonant conditions for the Klein-Gordon equation on the circle

Roberto Feola, Jessica Elisa Massetti

We consider the infinite dimensional vector of frequencies $ω (m) = (j^{2} + m)_{j \in Z}$ , $m \in [1, 2]$ arising form a linear Klein-Gordon equation on the one dimensional…

Reducibility of Klein-Gordon equations with maximal order perturbations

Massimiliano Berti, Roberto Feola, Michela Procesi +1

We prove that all the solutions of a quasi-periodically forced linear Klein-Gordon equation $ψ_{tt} - ψ_{xx} + m ψ + Q (ω t) ψ = 0$ where $ Q(ωt) := a^{(2)}(ωt, x) \partial_{xx} + a^…
