Global radial solutions to 3D relativistic Euler equations for non-isentropic Chaplygin gases (Q522633)

The authors study the relativistic perfect fluid equations in the Minkowski spacetime that converge to full Euler equations in the infinite light speed limit. The equation of state is the Chaplygin relation \(p\rho=-A(s)\) for some function \(A\). The initial data are spherically symmetrical and small perturbations of a constant state. The main result is the existence and uniqueness of a smooth solution to the system.
