Fast instability indicator in few dimensional dynamical systems
Piero Cipriani, Maria Teresa Di Bari
Using the tools of Differential Geometry, we define a new <<fast>> chaoticity indicator, able to detect dynamical instability of trajectories much more effectively, (i.e. "quickly"…

The (In)stability of Bianchi IX Dynamics: Geodesic Deviation Equations in Finsler Spaces
Maria Di Bari, Piero Cipriani
We explore the dynamical stability of the minisuperspace Hamiltonian of the Bianchi IX cosmological models, giving a gauge-invariant and unapproximated description of the full cont…
