报告题:On stability analysis for steady states of the free boundary hard phase model in general relativity

报告摘要:The hard phase model describes a relativistic barotropic fluid with sound speed equal to the speed of light. This model with free boundary admits a 1-parameter family of steady states. Within spherical symmetry, we prove linear stability for steady states with small central density and linear instability for large central density, where in the latter case we further demonstrate a dynamical nonlinear instability. This is a joint work with Zeming Hao.
