Mode conversion in inhomogeneous, nonstationary and nonlinear media
(description methods, exact solutions, waves generation, the effective dissipation
of energy, a wave barrier transillumination, the radiation of slow waves from the
inhomogeneous plasma, applications in plasmas and hydrodynamics). Coherent structures (large-scale instabilities, nonlinear stabilization,
the influence of helicity and rotation, structure forming precursors, numerical
simulations of coherent structure evolutions, applications in hydrodynamics, plasmas
and natural disasters forecasting),
