| Abstract: |

| We introduce a pressure-gradient system derived from the two-dimensional
compressible Euler system and we construct patches of solutions of the
2-D Riemann problems for the pressure-gradient system. In the self-similar
plane, we verify that there are elliptic regions, hyperbolic regions,
and sonic boundary parts. In addition, it is also verified that
there is a zone called semi-hyperbolic or partially hyperbolic in which
one family out of two nonlinear families of characteristics starts on sonic
curves and ends on transonic shock waves. |
