Characterizing dynamics with covariant Lyapunov vectors
F. Ginelli, P. Poggi, A. Turchi +3
A general method to determine covariant Lyapunov vectors in both discrete- and continuous-time dynamical systems is introduced. This allows to address fundamental questions such as…

Lyapunov exponents from unstable periodic orbits in the FPU-beta model
Roberto Franzosi, Pietro Poggi, Monica Cerruti-Sola
In the framework of a recently developed theory for Hamiltonian chaos, which makes use of the formulation of Newtonian dynamics in terms of Riemannian differential geometry, we obt…
