报告摘要:In this talk, we investigate the smooth spherically symmetric solutions to 3D relativistic Chaplygin gases with variable entropy, whose initial data is assumed to be a small smooth perturbation to a constant state. Due to the structure of the equation, we can still take advantage of the ``null condition'' which is satisfied by the potential equation for isentropic and spacetime irrotational relativistic Chaplygin gases and obtain the global existence of smooth solution by continuity method. Our method can also prove the global existence of smooth spherically symmetric solutions to the stiff matter. This is a joint work with Professor Zhen Lei.
