Abstract
We study a convective problem of `mixed type' (i.e., parabolic and hyperbolic) which has a degenerate second-order term. The analysis by the `vanishing viscosity' method is conducted by a careful study of the phase boundaries and of the topological structure of the phase sets. At the end we provide the existence of a discontinuous travelling waveFile in questo prodotto:
