ON SOME ASPECTS OF SYSTEMS THEORY

摘要

The aspects of systems theory presented here have to do with the theme of observation. The perception a system has of itself and its environment involves the inverse transfer of internal structures. It is completed by a kind of perception through decisions taken. Both are aspects of what we propose to call "epistemo-praxiology". Intrinsic or internal duration, adapted to a dynamical system, is another aspect of perception. The internal duration considered here is greater if the state of the system changes rapidly and is equal to zero when the state does not change. The square of the speed of evolution of the system, at a given instant, is proposed as a degree of importance of this instant. Application is given in the case of an explosive-implosive system with interpretations in physiology and cosmology.
