The selection rules for three-magnon splitting in a vortex-state magnetic disk are derived, the possibility to control the splitting channel by the excitation frequency is demonstrated. Theory of spin-wave mode spectrum in triangular frustum magnetic nanodots is developed; significant effect of static demagnetization fields nonuniformity on the spin-wave modes formation is found, which makes impossible application of classical methods for spin-wave spectra calculations based on the averaged field approximation.
