On the formation of discontinuities in 3d self-similar rarefaction flows

There are the automodelling cylindrical and spherical flows, which appear during a rarefaction of gas. It is a sharply depression a density of gas due to a decreasing mass of gas spreads to a increasing volume. It is a gradient's catastrophe. It will possible a avoidance this fact with such constraction. In point r=ro>0 an automodelling wave of rarefaction joins with a homogeneous rest gas and a new flow, which has a sigularity in point r=ro similar a sigularity of simple centered wave. It is a example a approximate joint of an automodelling wave of rarefaction with a homogeneous rest gas. In the moment of a focusing a weak discontinuity to the axis or to the center of symmetry it is a sharply depression a density of gas.
