Abstract
The governing equations of a dusty gas with cylindrical or spherical symmetry are considered. Using the commuting properties of the invariance groups of the system, we are able to characterize appropriate `canonicala variables allowing to reduce the equations to autonomous form. In this way, we characterize particular exact solutions and the propagation of weak discontinuities is considered in such non-constant states.File in questo prodotto:
