Chaotic Explosions
Eduardo G. Altmann, Jefferson S. E. Portela, Tamás Tél
We investigate chaotic dynamical systems for which the intensity of trajectories might grow unlimited in time. We show that (i) the intensity grows exponentially in time and is dis…
Chaotic Systems with Absorption
Eduardo G. Altmann, Jefferson S. E. Portela, Tamás Tél
Motivated by applications in optics and acoustics we develop a dynamical-system approach to describe absorption in chaotic systems. We introduce an operator formalism from which we…
Leaking Chaotic Systems
Eduardo G. Altmann, Jefferson S. E. Portela, Tamás Tél
There are numerous physical situations in which a hole or leak is introduced in an otherwise closed chaotic system. The leak can have a natural origin, it can mimic measurement dev…
