摘要
The Vlasov-Poisson and Vlasov-Einstein systems model the motion of a self gravitating system such as a galaxy. The Vlasov-Poisson system is nonrelativistic. Jeans' theorem states that every spherically symmetric solution of the Vlasov-Poisson system that is independent of time may be expressed as a function of the two invariants, energy and angular momentum, This paper shows this is not the case for the Vlasov-Einstein system.
