Phase transition in holmium ''along the magnetic field''

A random force method applied to turbulency in a compressible fluid is developed. It is shown that invariance of the characteristic functional equations under a group of scale transformations permits one to determine the turbulency spectrum in the inertial range for both a compressible and imcompressible fluid. Similar to the energy spectrum, the spectra of two-point semi-invariants of arbitrary order are calculated in the inertial range
