ABASTRACT:
Higher order waves in (relativistic) MHD
I will talk about our findings in simulations of linear waves in (R)MHD, which inevitably trigger higher order waves, which trigger even higher oder waves. Some of them are amplified, some of them are damped with time because of physical and numerical reasons. The prelimiary conclusions of our findings show that without a proper characterization of these non-linear effects, further analysis of linear modes and its saturation might be inadequate.
