Den speciella relativitetsteorin – en begreppsanalys av teorins logiska struktur

This paper presents a conceptual and logical analysis of the structure of the special theory of relativity (SR). The study focuses on the definitions of fundamental concepts such as distance, time, simultaneity, inertial frames, velocity, light propagation and coordinate systems. The analysis is based on an explicitly defined geometric analysis model (AM), which allows a direct comparison between geometric relations and coordinate descriptions of physical events. The purpose of the work is methodological: to clarify the logical structure of the concepts used in SR and the assumptions required to relate them. The results show how the relations between light propagation, reference frames and coordinate descriptions depend on the conceptual structure used in the theory. The work is part of a broader research program devoted to the conceptual analysis of special relativity and its foundational assumptions.
