To the expansion of the flat harmonic waves of small amplitudes in ultrarelativistic media

Abstract

The problem of the flat harmonic wave expansion in ultra-relativistic media is considered. Numerical solutions of dispersion equations for the waves of small amplitudes were obtained within the framework of different local relativistic models and non-local Alexeev hydrodynamics. It is shown that only non-local theory leads to meaningful results.
