Labyrinth Chaos: Conservative, non-Hamiltonian Chaos without Attractors
Vasileios Basios
Université Libre de Bruxelles, Interdisciplinary Centre for Nonlinear Phenomena & Complex Systems (Cenoli-ULB) & Département de Physique des Systèmes Complexes et Mécanique Statistique
Abstract:
We provide here a comprehensive proof that the so-called “Labyrinth Chaos”, of the Thomas-Rössler (TR) class of systems, cannot admit a Hamiltonian; yet it affords a vector potential.
“Labyrinth Chaos” is special since it has a countable infinity of unstable fixed points and does not possess any chaotic or other attractors. The proof starts from the general case of TR systems, which are in general non-conservative standard chaotic systems, and we proceed by showing that this is also true for their limit-case, known as `Labyrinth chaos', which is volume-preserving hence conservative.
To our knowledge, this is the first instance reported where a conservative chaotic system does not, in principle, admit a Hamiltonian, symplectic, structure. Still, a vector potential is readily admissible and thus, constructed.
