Abstract: This paper is considering a two-dimensional compressible Euler system for a class of pressure laws, a direct method is used to discuss the sufficient conditions for the existence of the characteristic decomposition and the decompositions of the pressure p and the characteristics Λ± are obtained. It is found that any wave adjacent to a constant state is a simple wave.
