Relativistic invariance of Lyapunov exponents in bounded and unbounded systems
Adilson E. Motter, Alberto Saa
The study of chaos in relativistic systems has been hampered by the observer dependence of Lyapunov exponents (LEs) and of conditions, such as orbit boundedness, invoked in the int…

Non-Gaussian features of chaotic Hamiltonian transport
Roberto Venegeroles, Alberto Saa
Some non-Gaussian aspects of chaotic transport are investigated for a general class of two-dimensional area-preserving maps. Kurtosis, in particular, is calculated from the diffusi…
