Global existence for a simplified model of nuclear fluid in one dimension. (English) Zbl 0974.76013

Summary: We consider a regularized one-dimensional hydrodynamical model of nuclear slab, with a van der Waals type pressure law, for which we identify asymptotically stable stationary states, and, for small data, prove global existence. We also describe the asymptotic behaviour of the system for large time, provided that the initial density is restricted to a pure phase region.
