The studying (together with R.Z.Sagdeev, G.M.Zaslavsky, V.N.Oraevsky, A.A.Galeev, E.Ya.Kogan) new types of plasma instabilities including dissipative, secondary and low-frequency thermal ones which worse the magnetized plasma confinement. In particular, the universal drift-dissipative instability was founded (together with R.Z.Sagdeev) which may exists both in the fully ionized plasma and partially ionized one (like the ionospheric plasma) and results to the very dangerous (for a plasma confinement in magnetic mirrors, for example, in tokamaks) turbulent Bohm diffusion.
