On the basis of two-fluid magnetohidrodynamic the nonlinear parametric interaction of the pump whistler wave with higth frequency electron acoustic wave and the inertial Alfven wave in the auroral magnetosphere with a low plasma parameter β is considered. The nonlinear dispersion equation for three-wave interaction, the growth rate and the time of development of the parametric decay instability are found. The theoretical results are used for the analysis of the experimental data obtained during satellite inverstigations.
