BASIC CONCEPTS OF SYSTEM THEORY

Abstract

Systems and systemic method; systems inside an environment, approximations. Role played by measurements when studying systems, limitations by measurements. Compounding observables leads to classify systems into 3 classes: C, α, β. State of a system, and state observable. Case of non-simultaneously measurable observables. Experimental statements: properties of their logical product. Geometrical representation of a system. Predictions and expression of the predictions. Systems with several levels. Structure of a system, relations between significant parts. Notation of predictions, cases of C-, α-, β-types. Evolution law, self-predictable observable, vectorial scheme.
