Abstract

This paper is concerned with the Riemann problem of Euler equations for one-dimensional generalized Chaplygin gas.Using characteristic analysis

we get the existence and uniqueness of the Riemann solutions.Different from the polytropic gas

the Euler equations for generalized Chaplygin Gas appear the mass concentration solution.
