A Principle of Coherent Definition in Physical Theories

This work proposes a foundational theoretical framework aimed at addressing conceptual consistency across physical theories. The paper introduces a principle of coherent definition, focusing on how physical quantities, laws, and theoretical structures acquire meaning through internally consistent definitional criteria. Rather than proposing a new dynamical model, the approach emphasizes structural coherence as a unifying requirement underlying classical, relativistic, and quantum descriptions. Mathematical formalism is employed to clarify the scope and limits of the principle, and implications for theory construction and interpretation are discussed.
