Dynamics of collisionless matter in Bianchi type I cosmologies |
We investigate the dynamics of spatially homogeneous Bianchi type I solutions of the Einstein-Vlasov equations. All models become singular towards the past -- we exhaustively describe the large variety of possible past asymptotic states. In this context we establish the existence of a heteroclinic network which replaces the Taub solutions as an asymptotic state. The past asymptotic structure illustrates that the dynamics of collisionless matter models differs significantly from that of perfect fluid models. |
