Purpose – To present the concept of inverse transfer of the internal structures of a dynamical system to the perception it has of its environment and itself.Design/methodology/approach – We use the formalism of mathematical operators acting on fu

Purpose – To give a mathematical expression of what could be called the internal time of a dynamical system, a time which is different from the external or reference time.Design/methodology/approach – The paper introduces a general mathematical d

The founders of cybernetics and systems are presented, among them N. Wiener, W.S. McCulloch and L. von Bertalanffy. Some precursors are cited from antiquity to 20th century. The basic concepts are exposed: feedback, quantity of information, requisite

We consider a dynamical linear differential (or recurrent) system whose initial state is given only by a probability density. The Shannon information entropy, associated with the probability density, is considered as a global uncertainty index giving

Harmonic analysis, probability and statistics were among the fields Wiener was most interested in. In his generalized harmonic analysis he introduced, for a signal with finite square modulus mean value, its spectral distribution which is linked to wh
