Solvability of the System of Equations of One-Dimensional Motion of a Heat-Conducting Two-Phase Mixture

We prove the local solvability of the initial boundary-value problem for the system of equations of one-dimensional nonstationary motion of a heat-conducting two-phase mixture (gas plus solid particles). For the case in which the real densities of the phases are constant, we establish the solvability “in the large” with respect to time.
