The method alternative to the approach of Ginzburg–Landau, intended for classification of equilibrium states of the degenerate condensed media with vector parameter of the order is created. Fermi-liquid approach is distributed on the description spiral magnetics and В-phase of a superfluid Fermi-liquid. Researches under the account of influence of the form and the sizes of Cooper pairs in superfluid Fermi-liquids on thermodynamics and nonequilibrium processes are executed. The opportunity of occurrence of new sounds in a superfluid liquid similar on structure on sounds in liquid crystals is predicted.

Rozhkov Alexander Alimovich, in 1984 worked as the teacher trainee on PTF KhSU. In 1985–1988 studied in postgraduate course in the same place, and in 1989 has protected the master's thesis in Institute of Monocrystals (Kharkov). With 1989 on 1994 (Kharkov), and then in SPTC up to 2005 worked in Institute of Monocrystals. Now I work as the teacher in NТU KhPI(Kharkov) in a post of the senior lecturer. Articles are published in magazines such as ECHAYA, ТМP, PLТ, Physica, Physical Review.
