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 where $ Q(ωt) := a^{(2)}(ωt, x) \partial_{xx} + a^…

KAM theory for the Hamiltonian derivative wave equation
Massimiliano Berti, Luca Biasco, Michela Procesi
We prove an infinite dimensional KAM theorem which implies the existence of Cantor families of small-amplitude, reducible, elliptic, analytic, invariant tori of Hamiltonian derivat…

Forced vibrations of wave equations with non-monotone nonlinearities
M. Berti, L. Biasco
We prove existence and regularity of periodic in time solutions of completely resonant nonlinear forced wave equations with Dirichlet boundary conditions for a large class of non-m…
