Reducibility of non-resonant transport equation on $T^{d}$ with unbounded perturbations

Dario Bambusi, Beatrice Langella, Riccardo Montalto

We prove reducibility of a transport equation on the $d$ -dimensional torus $T^{d}$ with a time quasi-periodic unbounded perturbation. As far as we know this is the first example of a…

Absolute continuity of the spectrum of coupled identical systems on 1D lattices

Beatrice Langella, Dario Bambusi

We prove that the spectrum of the discrete Schrödinger operator on $ℓ^{2} (Z^{2})$ , $(ψ_{n, m}) \mapsto - (ψ_{n + 1, m} + ψ_{n - 1, m} + ψ_{n, m + 1} + ψ_{n, m - 1}) + V_{n} ψ_{n, m}$ is absolutely continuo…
