The Riemann Problem for a 3x3 Generalized Chaplygin Gas System with Variable Pressure
For a 3x3 generalized Chaplygin gas with a transported pressure coefficient, the authors classify Riemann solutions and prove that isolated overcompressive delta shocks arise as zero-viscosity limits of Dafermos viscous profiles.
