Fluid Stabilization in Slowly Expanding Cosmological Spacetime

Explore a General Relativity Seminar presentation where David Fajman from Vienna discusses the fascinating phenomenon of fluid stabilization in expanding cosmological spacetimes. Learn how relativistic fluids, typically known to form shocks during evolution from near-homogeneous initial data, behave differently in expanding spacetimes where shock formation can be suppressed under sufficient expansion conditions. Discover recent findings about fluid stabilization occurring in spacetimes with slower expansion rates, moving beyond the well-studied regime of accelerated expansion. Delve into various recent results and methodological approaches used to prove fluid stabilization in slowly expanding spacetimes, gaining insights into the implications for structure formation and cosmological evolution.
