The Coupling-Interface Adaptive Flow Regulating Valve: A Dynamical Topological Mechanism for Global Determinacy and Local Indeterminacy

Based on the primitive axioms and geometric uniqueness of the Pythagorean Frustum Unified System (PFUS), this paper constructs a two-dimensional local adaptive flow regulating valve model on the coupling interface of the 45° coaxial double-cone structure, and presents the dynamical topological origin of indeterminacy. On the premise of maintaining global structural conservation, topological completeness and strict determinacy, the model naturally derives the nonpredictability of local instantaneous flux. This paper further reveals that the adaptive flow regulating valve is the core safety mechanism for the universe to maintain its own structural stability.
