The spectrum of edge magnetoplasma waves in GaAs-AlGaAs heterostructures has been studied under conditions corresponding to the quantum Hall effect for filling factors ν = 1,2,4 at temperatures of 0.4-4.2 K. The spectrum of the edge magnetoplasma waves is not equidistant. The resonant frequencies of these waves are proportional to ν (for integer values of v).
