Simple Waves and a Characteristic Decomposition
of the Two Dimensional Compressible Euler Equations
Jiequan Li, Tong Zhang, and Yuxi Zheng
We present a characteristic decomposition of the potential flow equation in
the self-similar plane. The decomposition allows for a proof that any wave
adjacent to a constant state is a simple wave for the adiabatic Euler system.
This result is a generalization of the well-known result on 2-d steady
potential flow and a recent similar result on the pressure gradient
