| 概要 | We describe the asymptotic behavior of small energy
solutions of an NLS with a trapping potential. In
particular we generalize work of Soffer and Weinstein, and
of Tsai and Yau. The novelty is that we allow generic
spectra associated to the potential. This is yet a new
application of the idea to interpret the nonlinear Fermi
Golden Rule as a consequence of the Hamiltonian structure.
This is a joint work with Scipio Cuccagna (Trieste
University). |
