| Research Abstract |
Toward understanding the formation mechanisms of non-uniform spatial structures in astrophysical and laboratory plasmas, general mode-coupling theory is developed for global (or long wavelength) fluctuations, for which the conventional local (or short wavelength) approximation is not valid. By developing new mathematical techniques that base on the theory of infinite-dimensional Hamiltonian system, the global mode-coupling, which may include continuous spectrum, is successfully formulated and it is applied to specific phenomena.
