Let … Webvacuum equilibrium, and later by Hoﬀ [14, 15] for discontinuous initial data. If the initial density need not be positive and may vanish in an open subset, then one has local strong solutions (also classical solutions); we refer the reader to [7, 8]. For the global existence of weak solutions with arbitrary initial data, the major breakthrough
