Abstract
Riemann problems for a class of 2×2 hyperbolic systems involving source-like terms are considered. By means of reduction techniques it is shown that the searched rarefaction wave is given by an exact solution which, in fact, represents a deformation of the rarefaction wave admitted by the corresponding homogeneous governing model. Hence the solution of the Riemann problem of interest is providedFile in questo prodotto:
