Resumen
The nonlinear dynamics of a nite-amplitude Alfv en wave in a dispersive modulational regime is analysed. Use is made of a conservative model to show that turbulence may arise via deterministic chaos. The behaviour of the system is studied as one varies the initial amplitude of the pump Alfv en wave, the dispersion parameter and the plasma parameter β.
