Nonlinear waves in open and closed systems:
dispersion vs. weak turbulence
Dynamics of weakly nonlinear waves (such as small amplitude water or gravitational
waves) depends crucially on whether the domains in which the waves propagate are
unbounded (open) or bounded (closed). On unbounded domains the evolution of waves
is stabilized by the dissipation of energy by dispersion, while on bounded domains the
evolution is destabilized by weak turbulence. In my talk, I will illustrate these two kinds
of behaviour first with simple examples and then with solutions of Einstein's equations.
