2nd Edition, as published by Charles François 2004 Presented by the Bertalanffy Center for the Study of Systems Science Vienna for public access.

About

The International Encyclopedia of Systems and Cybernetics was first edited and published by the system scientist Charles François in 1997. The online version that is provided here was based on the 2nd edition in 2004. It was uploaded and gifted to the center by ASC president Michael Lissack in 2019; the BCSSS purchased the rights for the re-publication of this volume in 200?. In 2018, the original editor expressed his wish to pass on the stewardship over the maintenance and further development of the encyclopedia to the Bertalanffy Center. In the future, the BCSSS seeks to further develop the encyclopedia by open collaboration within the systems sciences. Until the center has found and been able to implement an adequate technical solution for this, the static website is made accessible for the benefit of public scholarship and education.

SYSTEM (Conservative, or Hamiltonian, or non-dissipative) 2)

← Back

The ideal model for a conservative system is the pendulum devoid of friction, which in theory maintains an invariable movement and a constant energy.

This type of system may be represented by equations integrable without restrictions and its past and future behavior can be completely computed.

The theoretical simplification thus obtained is useful for the prediction of the behavior of those concrete systems whose energy is nearly constant and are controlled by only one dominant variable, as for example the planets in the solar system.

Perfect conservative systems (which do not exist in the real world), having a constant energy, would not be submitted to the 2d. Principle of thermodynamics, and be perfectly reversible and independent from time and, thus, have no attractor.

"Their evolution does not provoque any contraction of the areas in the phases space. "(P. BERGÉ et al., 1984, p.43).

L. BRILLOUIN did consider this question in depth, starting from POINCARÉ's ideas, in Chapter VI of his book "Vie, Matiere et Observation", under the heading: "POINCARÉ: l'Energétique et le déterminisme" (1959, p.195-217). See also his comments on the related LIOUVILLE theorem (Ibid, p.181-191).
