abstract
We consider a U (1)-invariant nonlinear Klein-Gordon equation in dimension n 1, self-interacting via the mean field mechanism. We analyze the long-time asymptotics of finite energy solutions and prove that, under certain generic assumptions, each solution converges as t to the two-dimensional set of all "nonlinear eigenfunctions" of the form {symbol} (x) e- i t. This global attraction is caused by the nonlinear energy transfer from lower harmonics to the continuous spectrum and subsequent dispersive radiation. 2008 Elsevier Masson SAS. All rights reserved.
