Conclusions
Conclusions◮ Unstable modes may be saturated by resonant processes◮ Damped modes may reach substantial amplitudes◮ Limit cycles: Low-frequency modulation (time scale ∝ 1/γ 3 )Main question = damping◮ α-viscosity seems to be insuficient◮ MHD turbulence, disipation◮ accretion(reduces excitation rate and increases damping rates)Other quastions◮ Role of the additional internal resonances (e.g. 1 : 2 : 3)◮ Saturation of other global instabilities.→ MRI [linear analysis by Curry & Pudritz 95]
