Abstract:
We consider a formula9-invariant nonlinear Klein-Gordon equation in dimension formula11, 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 formula13 to the two-dimensional set of all ``nonlinear eigenfunctions'' of the form formula15. This global attraction is caused by the nonlinear energy transfer from lower harmonics to the continuous spectrum and subsequent dispersive radiation.
