Topological and percolation properties of potential mapping with glueing.
The potential movement of particles forms a continuous mapping of the Lagrangian space on the space of Eulerian coordinates of particles. The force-free inertial movement with random smooth initial velocity field is considered. The condition of particles on caustics glued together to form singularities leads to a peculiar structure with localized regions of rarefied matter surrounded by glued surfaces with higher-order singularities on them.
