Structural Non-Derivability and Boundary Collapse: A Formal Response to Reductionist Critiques
Year: 2026
Type: article
Abstract: Structural collapse events—such as cosmological singularities, biological transitions, financial crises, or training instability in machine learning—share a common feature: the internal dynamical laws governing the system cease to be derivable at specific structural boundaries. This paper introduces a formal framework for structural non-derivability in state-space dynamics. This paper clarifies the formal foundations of the Theory of Non-Derivable Admissibility (TNA) and provides a definitive response to reductionist critiques that attempt to equate structural collapse with classical bifurcation or catastrophe theory. We demonstrate that the framework concerns the limits of derivability of dynamical operators rather than qualitative transitions within an existing domain of validity. By defining an admissible structural domain $\Omega_S$ and its non-derivable boundary $\partial \Omega_S$, we prove that systemic collapse is a geometric consequence of reaching the limits where internal dynamical laws cease to be applicable. Drawing a formal parallel with Gödelian incompleteness, the paper establishes that operational systems depend on structural conditions that they cannot internally generate. This formulation provides a rigorous, cross-disciplinary metric for structural rupture, reaffirming that intelligibility in complex systems is fundamentally retrodictive when crossing structural boundaries. Core Reference: This work is an integral component of the Theory of Axiomatic Necessity (TNA) framework developed by Claudio Bresciano. It formalizes specific domain constraints within the global $N_1$ structural logic.
