Ramanujan’s tau function, Taniyama-Shimura conjecture and Wiles’ proof of Fermat’s Last Theorem are three number-theoretic projections of biconical topology. The multiplicativity of tau function reflects latching stress coupling of prime anchor points on the bicone waist-ring. The modular form-elliptic curve correspondence proves isomorphic mapping between upper and lower cone projection layers. Fermat’s Last Theorem verifies that complete 3D topological closure cannot exist without standard biconical steady-state conditions. This paper divides mathematics into ontology, abstraction and tool layers, and offers a unified topological interpretation for classic number theory results without modifying existing mathematical proofs.
