摘要：

We investigate the low-energy spectrum of excitations of a compressible electron liquid in a strong magnetic field. These excitations axe localized at the periphery of the system. The analysis of a realistic model of a smooth edge yields new branches of acoustic excitation spectrum in addition to the well known edge magnetoplasmon mode. The velocities are found and the observability conditions are established for the new modes.
