Query: Spectral and Intermittency Properties of Relativistic Turbulence   High-resolution numerical simulations are utilized to examine isotropic
turbulence in a compressible fluid when long wavelength velocity fluctuations
approach light speed. Spectral analysis reveals an inertial sub-range of
relativistic motions with a broadly 5/3 index. The use of generalized
Lorentz-covariant structure functions based on the four-velocity is proposed.
These structure functions extend the She-Leveque model for intermittency into
the relativistic regime.
