Annotation	We consider an initial-boundary value problem for the equations of spherically symmetric motion of a pressureless gas with temperature-dependent viscosity mu(theta) and conductivity kappa(theta). We prove that this problem admits a unique weak solution, assuming Belov's functional relation between mu(theta) and kappa(theta) and we give the behaviour of the solution for large times.
