Аннотация The plasma oscillations of the two-dimensional electron-hole system in the presence of a strong perpendicular magnetic field are studied. Only the intra-Landau level excitations are taken into account when the electrons and holes are situated on their lowest Landau levels, the filling factor v2 being less than 1. The ground state of the two-dimensional e-h system is supposed to be the electron-hole liquid. The dispersion relations for the optical and acoustical plasmon modes were obtained. The influence of the supplementary in-plane electric field acting side by side with the strong perpendicular magnetic field is discussed.
