The report summarizes the activities and results obtained during the tenure of the Grant. The relaxation problem of the Fokker-Planck collision operator is investigated. Comparison are made between the relaxation times of the Brownian Motion and the BGK collision operators. The AC electrical conductivity and the high-frequency electrical conductivity formulas for a fully ionized gas are derived. A new mechanism of an ionizing wave front is introduced. Its structure and propagation is studied. Criteria for instabilities are found. The effect of a samll amount of collisions on the stability of ion acoustic waves, drift waves, etc are considered.
