Existence of weak solutions to the problem on three-dimensional steady heat-conductive motions of compressible viscous multicomponent mixtures

We consider the equations describing the three-dimensional steady heat-conductive motions of compressible viscous multicomponent mixtures. We also prove the existence of weak solutions to the boundary value problem in a bounded domain without any simplifying assumptions on the structure of the viscosity matrix except for the standard physical requirement of positive definiteness.
