Abstract: Consider the stability of relativistic star clusters modeled by Vlasov-Einstein system. The above question arose in the 1960s with the discovery of quasars, which exhibit high redshift. I will discuss results which illustrate the fact that as the central redshift increases, the steady states change from being stable to being unstable. I will also discuss the structure of the linearized equation near an unstable steady solution and the relation to critical phenomena of gravitational collapse for Vlasov-Einstein model. This is joint work with Mahir Hadzic and Gerhard Rein.
