The conceptual analysis (CA) method in theories of microchannels: Application to quantum theory. Part I. Fundamental concepts

Abstract

A method is proposed that should facilitate the construction of theories of “submicroscopic particles” (denoted as “theories of microchannels”) in a way similar to the use of group-theoretical methods. The “conceptual analysis” (CA) method is based on the analysis of the basic concepts of a theory; it permits a determination of necessary conditions imposed on the mathematical apparatus (of the theory) which then appear as a mathematical representation of the structures obtained in a formal scheme of a theory. A pertinent conceptual analysis leads to a new definition (“relativization”) of the concept “empirical implication.” The approach may be characterized as “realistic” and “operational.” The application of the CA method is illustrated on the example of quantum theory. In Part I the algebraic structure of a partially ordered, up-ward directed, bounded set is deduced from the rudimentary concepts. In Parts II and III, we shall deduce the Hilbert-space structure (well established in quantum mechanics) from postulates on some essential idealizations accepted in the theory. Whereas Part II is concerned with the idealizations of existing quantum theories based on the Hilbert-space formalism, Part I may be considered as a general basis for a wider class of theories.
