Summary: We report computation of the Kolmogorov-Sinai entropy in a variety of simple liquids studied by molecular dynamics. It is found that this quantity, when expressed in terms of the atomic collision frequency, is uniquely related to the thermodynamic excess entropy by a universal linear scaling law.

Chaotic disturbance rejection a Kolmogorov-Sinai entropy approach
Proceedings of 32nd IEEE Conference on Decision and Control, 2002This paper deals with disturbance rejection, when the external disturbance signal is a chaotic process. The authors measure the amount of chaos by the Kolmogorov-Sinai entropy. The natural question is the extent to which the Kolmogorov-Sinai entropy is reduced by means of a feedback.

Chaos in three-body dynamics: Kolmogorov--Sinai entropy
Monthly Notices of the Royal Astronomical Society, 1999An ensemble of Newtonian three-body models with close initial separations is investigated by following the evolution of a ‘drop’ in the homology map. The onset of chaos is revealed by the motion and the complex temporal deformation of the drop. In the state of advanced chaos, the drop spreads over almost the whole homology map, quite independently of ...

Mutual Kolmogorov-Sinai entropy approach to nonlinear estimation
[1992] Proceedings of the 31st IEEE Conference on Decision and Control, 2005For a general nonlinear estimation problem, the authors develop an upper bound on the correlation coefficient in terms of the mutual Komogorov-Sinai entropy. This upper bound may be reached by means of a nonlinear transformation such that, after transformation, the processes are jointly Gaussian.

On the relation between the divergence of trajectories and the Kolmogorov-Sinai entropy
Physics Letters A, 1976Abstract Automorphisms of the torus are considered and the Kolmogorov-Sinai entropy explicitly computed via rate of growth of volumes. The usual rate of growth of exponentiating trajectories is shown to give only a lower bound to K-S entropy.

Comments on the Kolmogorov-Sinai-S siada entropy and the quantum information theory
Reports on Mathematical Physics, 1976Abstract Commenting the recent generalization by S a siada of the Kolmogorov-Sinai entropy to the quantum case ( KSS entropy ), it is remarked that this entropy refers to the process of evolution as a whole and to the initial state ( t = 0), not to the state at any time ( t ⩾ 0). Therefore, the KSS entropy has no direct relation to the von
