    The author defines the harmonic and wave maps up to rearrangement. These are the critical points of a variational functional for Laplace or wave equation up to the rearrangments of the space. The connection between harmonic maps up to rearrangement and gas dynamics (isothermal irrotational inviscid gas) is shown. The used methods are variational techniques and functional analysis.
