    "abstract": "We investigate the compression of nuclear matter in relativistic\nhydrodynamics. Nuclear matter is described by a $\\sigma-\\omega$--type model for\nthe hadron matter phase and by the MIT bag model for the quark--gluon plasma,\nwith a first order phase transition between both phases. In the presence of\nphase transitions, hydrodynamical solutions change qualitatively, for instance,\none-dimensional stationary compression is no longer accomplished by a single\nshock but via a sequence of shock and compressional simple waves. We construct\nthe analytical solution to the ``slab-on-slab\u0027\u0027 collision problem over a range\nof incident velocities. The performance of numerical algorithms to solve\nrelativistic hydrodynamics is then investigated for this particular test case.\nConsequences for the early compressional stage in heavy--ion collisions are\npointed out.",
