Global properties of quasiaveraged equations of one-dimensional motion of a viscous heat conducting gas
We study the initial-boundary value problem for the system of quasiaveraged equations in the case when the medium is a polytropic perfect gas. We obtain a theorem on the existence of a generalized solution ``in the large'' in time and for nonsmooth data. We establish theorems on regularity and uniqueness of solution, which are also new for the original equations of motion of a nonhomogeneous gas.
