Covariant Lyapunov Exponents for the Mixmaster
arXiv:gr-qc/0402019 · doi:10.1142/9789812704030_0221
Abstract
The dynamics of the Mixmaster Universe is analized in a covariant picture via Misner--Chitre-like variables for an ADM Hamiltonian approach. The system outcomes as isomorphic to a billiard on the Lobachevsky plane and Lyapunov exponents are calculated explicitly.
