PFUSRC-16 PFUSRC Universal Space, Structural Isomorphism to Banach–Hilbert Spaces, and Proof of Cosmic Ontological Completeness

Based on the PFUSRC universal unified system as the sole primordial framework, this paper starts from ontological existence, independently constructs and rigorously proves the ontological structure and geometric uniqueness of the 45° coaxial double-cone. It systematically demonstrates the rigid structural isomorphism between PFUSRC universal space and Banach spaces as well as Hilbert spaces, and completes a self-consistent proof of cosmic ontological completeness. As abstract mathematical tools,
