✦ Synopsis

We consider turbulent 4-wave interaction of two types of waves: acoustic waves dispersion v s k and Ž 2 2 2 . Ž . electromagnetic-type waves dispersion V s m q p . For large wave vectors k 4 m , when the dispersion of EM-type waves becomes quasiacoustic, the stationary spectra are obtained following a standard Zakharov approach. In the small wave Ž . number region k, p < m we derive nonlinear differential Kompaneets-type kinetic equation for arbitrary distributions of the interacting fields and find when this equation has Kolmogorov-type power law solutions.
